When her dad gets hurt in a freak accident on Friday the 13th, Kerri is sure she's to blame, but then a boy shows up wearing her father's old sweatshirt, and Kerri's luck suddenly does a 180. Convinced that Connor Murphy is the talisman she needs to change her fate, Kerri begs him to be there for her while her dad is recuperating.

Her dad's in prison for murder, her mom drowns her sorrows every night at Dave's Dive, and Lexus is just trying to survive the cruelties of high school as a painfully shy bookworm with a bad wardrobe, and a collection of nervous habits.

Suddenly, she finds herself sucked into Girl World as a new member of the social elite dubbed "The Plastics".

When Zach Hastings and I get into a wrong-number mix-up, we don't follow the rules. We keep texting and flirting because he's wicked funny and perfectly nerdy and a wonderful distraction. I'm not looking for love, and Zach definitely had the wrong number. But maybe...maybe he's the right guy. 

Twelve-year-old Shayla is allergic to trouble. All she wants to do is to follow the rules. (Oh, and she’d also like to make it through seventh grade with her best friendships intact, learn to run track, and have a cute boy see past her giant forehead.) But in junior high, it’s like all the rules have changed. Now she’s suddenly questioning who her best friends are and some people at school are saying she’s not black enough. Wait, what?

Cooper Redmond has only one thing on his mind: tagging as many bases as possible by the end of sophomore year.

But when Coop is paired with the infamous “Hot Dog” Helen for a semester-long Health project on safe sex, his hopes of making it to the Majors are suddenly DOA. It’s going to take something seriously epic to resuscitate his reputation.

Life as a teenager is never easy. But for Natalee Murray, things have just gotten way more difficult.

When I left for college, I put 1,000 miles between my future and my past. I'd made a choice - I was going to cross back to the other side, to live with the living. I just didn't know how. And then I met Nate Preeter. An All-American baseball player, Nate wasn't supposed to notice a ghost-of-a-girl like me. But he did. He shouldn't want to know my name. But he did. And when he learned my secret and saw the scars it left behind, he was supposed to run. But he didn't.

Born into a life of privilege and secrets, Nora Blakely has everything any 19-year-old girl could desire. She's an accomplished pianist, a Texas beauty queen, and on her way to Princeton after high school. She's perfect. Leaving behind her million-dollar mansion and Jimmy Choos, she becomes a girl hell-bent on pushing the limits with alcohol, drugs, and meaningless sex. Then she meets her soul mate. But he doesn't want her.

Noah Derwin knows what it's like to be different. Being a 17-year-old kid in high school with blue hair, piercings, a mostly all black wardrobe, and an obsession with zombies and video games, he doesn't exactly blend in. But he never wanted to. His two dads raised him to always stay true to himself. Being gay in high school isn't exactly rainbows and butterflies, and Noah has definitely faced his fair share of bullies.

I'm Mackenzie Wellesley, and I've spent my life avoiding the spotlight. But that was four million hits ago... Blame it on that grade school ballet recital, when I tripped and pulled the curtain down, only to reveal my father kissing my dance instructor. At Smith High, I'm doing a pretty good job of being the awkward freshman people only notice when they need help with homework. Until I send a burly football player flying with my massive backpack, and make a disastrous - not to mention unwelcome - attempt at CPR.

Matt Gratton and his two best friends, Sean and Coop, always set themselves a summer-time goal. This year’s? To see a real-live naked girl for the first time. As far as Matt is concerned, they’d have better luck finding the lost city of Atlantis. But seeing a girl in the buff starts to seem like child’s play compared to the other summertime goal Matt sets for himself: to swim the 100-yard butterfly (the hardest stroke known to God or man) in order to impress Kelly West, the hot new girl. So what if he can’t manage a single lap, let alone four?
