Before Sloane, Emily didn't go to parties, she barely talked to guys, and she didn't do anything crazy. Enter Sloane, social tornado and the best kind of best friend - someone who yanks you out of your shell. But right before what should have been an epic summer, Sloane just...disappears. No note. No calls. No texts. No Sloane. There's just a random to-do list with 13 bizarre tasks that Emily would never try. But what if they can lead her to Sloane? "Go Skinny Dipping?" Um...

They didn't mean it. They didn't mean to hit the boy. There was a party, and it was an accident... that wasn't who they were. They were pre-law, a football player, bound for New York. No one could know, so Barry, Julie, Helen, and Ray swore one another to secrecy. But now, a year later, someone knows. Julie receives a haunting, anonymous threat: "I know what you did last summer." The dark lie is unearthed, and before the four friends know it they need to outsmart a killer... or they will be the next to die.

We weren't always like this. We used to be average New York City high school sophomores. Until our homeroom went for flu shots. We were prepared for some side effects. Maybe a headache. Maybe a sore arm. We definitely didn't expect to get telepathic powers. But suddenly we could hear what everyone was thinking. Our friends. Our parents. Our crushes. Now we all know that Tess is in love with her best friend, Teddy. That Mackenzie cheated on Cooper. That, um, Nurse Carmichael used to be a stripper.

Pay close attention, and you might solve this. On Monday afternoon five students at Bayview High walk into detention. Bronwyn, the brain, is Yale-bound and never breaks a rule. Addy, the beauty, is the picture-perfect homecoming princess. Nate, the criminal, is already on probation for dealing. Cooper, the athlete, is the all-star baseball pitcher. And Simon, the outcast, is the creator of Bayview High's notorious gossip app. Only Simon never makes it out of that classroom. Before the end of detention, Simon's dead.

I was brave. She was reckless. We were trouble. Best friends Caddy and Rosie are inseparable. Their differences have brought them closer, but as she turns 16 Caddy begins to wish she could be a bit more like Rosie - confident, funny and interesting. Then Suzanne comes into their lives - beautiful, damaged, exciting and mysterious - and things get a whole lot more complicated. As Suzanne's past is revealed and her present begins to unravel, Caddy begins to see how much fun a little trouble can be.

I'm a girl who believes in science and facts. Not fate. Not destiny. Or dreams that will never come true. I'm definitely not the kind of girl who meets a cute boy on a crowded New York City street and falls in love with him. Not when my family is 12 hours away from being deported to Jamaica. Falling in love with him won't be my story.

Theodore Finch is fascinated by death, and he constantly thinks of ways he might kill himself. But each time, something good, no matter how small, stops him. Violet Markey lives for the future, counting the days until graduation, when she can escape her Indiana town and her aching grief in the wake of her sister's recent death. When Finch and Violet meet on the ledge of the bell tower at school, it's unclear who saves whom.

Yale hopeful Bronwyn has never publicly broken a rule. Sports star Cooper only knows what he's doing in the baseball diamond. Bad boy Nate is one misstep away from a life of crime. Prom queen Addy is holding together the cracks in her perfect life. And outsider Simon, creator of the notorious gossip app at Bayview High, won't ever talk about any of them again. He dies 24 hours before he could post their deepest secrets online. Investigators conclude it's no accident. All of them are suspects. Everyone has secrets, right? What really matters is how far you'll go to protect them.

Marin hasn't spoken to anyone from her old life since the day she left everything behind. No one knows the truth about those final weeks. Not even her best friend, Mabel. But even thousands of miles away from the California coast, at college in New York, Marin still feels the pull of the life and tragedy she's tried to outrun. Now, months later, alone in an emptied dorm for winter break, Marin waits. Mabel is coming to visit, and Marin will be forced to face everything that's been left unsaid and finally confront the loneliness that has made a home in her heart.

Everyone thinks they know Libby Strout, the girl once dubbed "America's Fattest Teen". But no one's taken the time to look past her weight to get to know who she really is. Following her mom's death, she's been picking up the pieces in the privacy of her home, dealing with her heartbroken father and her own grief. Now Libby's ready: for high school, for new friends, for love, and for every possibility life has to offer.

Andie has a plan. And she always sticks to her plan. Future? A top-tier medical school. Dad? Avoid him as much as possible (which isn't that hard considering he's a congressman and he's never around). Friends? Palmer, Bri, and Toby - pretty much the most awesome people on the planet. Who needs anyone else? Relationships? No one's worth more than three weeks. So it's no surprise that Andie's got her summer all planned out, too.

Eleanor is the new girl in town, and she's never felt more alone. All mismatched clothes, mad red hair and chaotic home life, she couldn't stick out more if she tried. Then she takes the seat on the bus next to Park. Quiet, careful and - in Eleanor's eyes - impossibly cool, Park's worked out that flying under the radar is the best way to get by. Slowly, steadily, through late-night conversations and an ever-growing stack of mix tapes, Eleanor and Park fall in love. They fall in love the way you do the first time, when you're 16, and you have nothing and everything to lose.

Everything about Jessie is wrong. At least that's what it feels like during her first week of junior year at her new ultra-intimidating prep school in Los Angeles. Just when she's thinking about hightailing it back to Chicago, she gets an email from a person calling themselves Somebody/Nobody (SN for short), offering to help her navigate the wilds of Wood Valley High School. Is it an elaborate hoax? Or can she rely on SN for some much-needed help?

When it comes to relationships, Colin Singleton's type is girls named Katherine. And when it comes to girls named Katherine, Colin is always getting dumped. Nineteen times, to be exact. On a road trip miles from home, this anagram-happy, washed-up child prodigy has ten thousand dollars in his pocket, a bloodthirsty feral hog on his trail, and an overweight Judge Judy-loving best friend riding shotgun - but no Katherines.

Miles Halter is fascinated by famous last words - and tired of his safe life at home. He leaves for boarding school to seek what the dying poet Francois Rabelais called the "Great Perhaps." Much awaits Miles at Culver Creek, including Alaska Young. Clever, funny, screwed-up, and dead sexy, Alaska will pull Miles into her labyrinth and catapult him into the Great Perhaps.

Looking for Alaska brilliantly chronicles the indelible impact one life can have on another.
