An emotionless world where feelings are a commodity. A murderer pursuing a homecoming queen. These suspenseful novels showcase teenage ingenuity. WITH THRILLERS ON THE RISE 1? young adult literature, novelists are asking a question that adult authors and filmmakers have posed for years: "Who can you really trust?" The difference is that with Y.A., the answer generally isn't nobody. It's not that the stakes aren't high for teenagers. In four new novels, love, friendship and identity prove to be fraught - even deadly - propositions. Still, at some point in their struggle, the main characters decide to trust someone. And that, as the poet says, makes all the difference. s. E. grove's provocative new novel, the WANING AGE (Viking, 273 pp., $18.99; ages 12 and up), isn't overtly political, but it extrapolates from what might gently be called the downward trend in empathy in some pockets of America. Natalie Peña is an 18-yearold hotel maid living in San Francisco in a dystopian near-future. In her desensitized world, people lose all capacity for emotion at about 10, psychotic gangs called Fish ravage the city, and hateful 1-percenters buy "synaffs" from a pharmaceutical behemoth named RealCorp just so they can feel. Love, fury and agony have become playthings and status symbols - Botox for the heart. This being a dystopian novel, the folks at RealCorp clearly aren't the good guys. Early on, Natalie discovers that they've kidnapped her precious 11-year-old brother, Calvino, for testing. Calvino has never "waned," possibly because of the trauma surrounding his mom's death. He is a true empath and hence an invaluable lab rat. Grove, author of the "Mapmakers" trilogy, mixes action, noir, bram science and moral philosophy here. The book has its shaggy moments, as when it bogs down by distinguishing emotions from instincts. But at its best, "The Waning Age" is visceral and disarmingly smart. Natalie's quest to free Cal - and Cal's increasingly desperate loneliness at RealCorp - becomes gripping. And Grove refuses to write down to her audience, which makes her kin to her main character. Natalie may just barely remember what it means to feel, but she's as defiant and loyal a big sister as anyone could ask for. IT'S been said that there are only seven plots in existence: the slaying of a monster, the rise from rags to riches and so on. Karen M. McManus's debut smash, "One of Us Is Lying," a crackling murder mystery about high school detention, reminded us to add an eighth to the list: "The Breakfast Club." Her new novel, two can keep a secret (IF ONE IS DEAD) (Delacorte, 352 pp., $19.99; ages 12 and up), may be titled and packaged to look as much like a sequel as the law will allow, but it's actually a different beast - unfortunately, a tamer one. The new novel is set in Echo Ridge, Vt., that "Echo" being a wink from the author: It seems that whoever killed the homecoming queen five years ago has either returned or inspired a gloating copycat now targeting this year's festivities. "Two" unspools more slowly than "One," and the mystery doesn't deepen as the townspeople gossip - it just gets more convoluted. We warm to the alternating narrators as they warm to each other: Malcolm, "the band nerd with the disreputable family," and Ellery, the true-crime buff whose mom is in rehab. But there's a solar system of others meant to distract us from the true killer and, honestly, they're just kind of distracting. McManus is a gifted writer with a devious mind for crime. She could have done more to transform these scary-movie tropes, just as she jolted "The Breakfast Club." Both her novels trade on the idea that even teenagers have secrets worth lying and possibly dying for - which is empowering, in an odd way. But "Two Can Keep a Secret" is a holding gesture rather than an advance. Read it, but know that McManus has more electrifying novels to come. WHAT ARE HEROIC KNIGHTS supposed to do once they've finished saving the kingdom and it's time to break up the band? Open a theme restaurant? Release solo albums? E. K. Johnston's sly, funny, foamy adventure THE AFTERWARD (Dutton, 337 pp., $17.99; ages 12 and up) intertwines a quest to vanquish an evil old god with the aftermath of the expedition, in which our heroes try to establish a new normal in a world where people sing ballads about their awesomeness. "The Afterward" is written as Arthurian high fantasy and takes place in a land called Cadrium, which, appealingly, doesn't have our dogmatic notions of gender and sexuality. Virtually everyone in the brave cast of characters is a young woman or identifies as such. What pulls you along, more than the scuffling over an all-powerful "godsgem," is the love story between the thrill-seeking thief named Olsa and the stouthearted apprentice Kalanthe, whom she sweetly refers to as "my brave nearlya-knight." The structure of "The Afterward" is trickier than it needs to be. It not only moves back and forth through time but also alternates between first and third person. (Whoever decided that the book could forgo the convention of putting characters' names at the beginning of each chapter they narrated was ... incorrect.) But the gender flip is effortless and enlivening: "I leaned into her, and she looked down at me. Then, because I was a thief, I stole a kiss." Even the less vivid chapters have rousing set pieces, and Johnston's love for storytelling is catching. Here's hoping "The Afterward" becomes the first m a series. Kalanthe and Olsa's happily ever after will be like no one else's. the first test of a whodunit is how heartstopping and strange a thing has actually been dun. In SPIN (Scholastic, 400 pp., $17.99; ages 12 and up) Lamar Giles (no relation) nails the murder: An up-and-coming young D. J. named Paris Secord is found in an "almost religious" tableau, slumped over her turntables and bleeding from the head. Giles also puts a pair of memorable "detectives" on the case: two of Paris's sharp-elbowed high school friends, Kya and Fuse, who formerly vied for her attention. The girls try to set aside their mutual distrust and team up to solve their friend's killing, partly to exonerate themselves but mostly because they don't trust the police to understand how deeply Paris's life mattered. "Spin" has jolts and misdirection. It has duplicitous bloggers, avaricious music executives and sadistic fans in white masks. But what's even more impressive is the subtle stuff you almost don't notice because Giles wears his intellect so lightly: the masterly knowledge of hip-hop and R&B; the command of technology's uses and abuses; the discerning ear for the way high schoolers talk, both to one another and to grown-ups. Giles understands the complex force field between generations. He knows that when parents and grandparents say they "expect more" from teenagers, it's often because they haven't bothered to figure out who the teenagers actually are. A two-time nominee for an Edgar (as in Allan Poe) award, Giles is also a terrific plotter. Yes, there's a character who so obviously might be the murderer that he/she can't possibly be the murderer. But evaluating suspects is part of the ritual and the fun, and everyone here feels palpably real. At one point, someone compares Kya and Fuse to Veronica Mars. He may not know what a compliment that is. "Spin" champions the resourcefulness of teenagers and pities the grown-ups - villainous or just clueless - who underestimate them.

A dead body in the middle of the road (the high school's science teacher) welcomes twins Ellery and Ezra Corcoran, 17, to their new home in Echo Ridge, Vt., where they've been sent to live with their estranged grandmother during their mother Sadie's court-appointed rehab for opioid addiction. Ellery, a true-crime buff, uses the opportunity to look into Echo Ridge's notorious unsolved mysteries: the disappearance of Sadie's identical twin sister after Sadie was crowned homecoming queen 23 years earlier, and the murder of Lacey Kilduff, the homecoming queen found strangled at Murderland, the local Halloween theme park, five years ago. After the science teacher dies, Ellery is nominated for the homecoming court, and someone begins to threaten Ellery and the other two nominees for queen, tagging signs and promising a Murderland redux. When one of the two possible queens goes missing, Ellery dons her amateur detective hat, putting herself and her loved ones in danger. With complex characters and intricate plotting, McManus (One of Us Is Lying) delivers a fast-paced, twisty whodunit. Ages 14-up. Agent: Rosemary Stimola, Stimola Literary Studio.

McManus follows up her smash hit debut, One of Us Is Lying (2017), with another twisted mystery centered around wily teens. Echo Ridge is an idyllic small town in all ways but one: five years ago, homecoming queen Lacy Kildare was strangled, her body left in the presciently named Murderland theme park. The park changed its name, but the town never moved on Lacy's body may have been the first one to turn up, but she wasn't the first girl to go missing. Ellery and her twin brother, Ezra, have just moved to Echo Ridge to live with their grandmother while their mom, whose own twin vanished in high school, undergoes a stint in rehab. When another girl goes missing, true-crime obsessive Ellery is determined to find the truth. But Echo Ridge is dangerous, and she and her family may be more involved than she knows. This is as much a social commentary as it is a layered mystery, and a somewhat abrupt finale won't keep readers from speeding their way to the end.--Maggie Reagan Copyright 2018 Booklist
