Olive Torres is used to being the unlucky twin: from inexplicable mishaps to a recent layoff, her life seems to be almost comically jinxed. By contrast, her sister Ami is an eternal champion...she even managed to finance her entire wedding by winning a slew of contests. Unfortunately for Olive, the only thing worse than constant bad luck is having to spend the wedding day with the best man (and her nemesis), Ethan Thomas.

Perpetual daydreamer Liz Buxbaum gave her heart to Michael a long time ago. But her cool, aloof forever crush never really saw her before he moved away. Now that he’s back in town, Liz will do whatever it takes to get on his radar - and maybe snag him as a prom date - even befriend Wes Bennet. The annoyingly attractive next-door neighbor might seem like a prime candidate for romantic-comedy fantasies, but Wes has only been a pain in Liz’s butt since they were kids. Yet, somehow, Wes and Michael are hitting it off, which means Wes is Liz’s in.

When 17-year-old Rune Kristiansen returns from his native Norway to the sleepy town of Blossom Grove, Georgia, where he befriended Poppy Litchfield as a child, he has just one thing on his mind: Why had the girl who was one half of his soul, who promised to wait faithfully for his return, cut him off without a word of explanation?

Waverly Lyons has been caught in the middle of her parents’ divorce for as long as she can remember. This summer, the battle rages over who she’ll spend her vacation with, and when Waverly’s options are shot down, it’s bye-bye Fairbanks, Alaska, and hello Holden, Florida, to stay with her aunt. Coming from the tundra of the north, the beach culture isn’t exactly Waverly’s forte. The sun may just be her mortal enemy, and her vibe is decidedly not chill. To top it off? Her ability to swim is nonexistent.

American Ella Durran has had the same plan for her life since she was 13: study at Oxford. At 24, she’s finally made it to England on a Rhodes Scholarship when she’s offered an unbelievable position in a rising political star’s presidential campaign. With the promise that she’ll work remotely and return to DC at the end of her Oxford year, she’s free to enjoy her Once in a Lifetime Experience. That is until a smart-mouthed local who is too quick with his tongue and his car ruins her shirt and her first day.

Spencer covets her sister's boyfriend. Aria's fantasizing about her English teacher. Emily's crushing on the new girl at school. And Hanna uses some ugly tricks to stay beautiful. But they've all kept an even bigger secret since their friend Alison vanished.

Hi, my name is Bree Camden, and I’m hopelessly in love with my best friend and star quarterback Nathan Donelson (so is half of America, judging by the tabloids and how much the guy dates). The first step is admitting it, right? Except, I can never admit it to him because he clearly doesn’t see me that way, and the last thing I want is for things to get weird between us. Nothing but good old-fashioned no-touching-the-sexiest-man-alive platonic friendship for us! Everything is exactly how I like it! Yes. Good. (I’m not crying; I’m just peeling an onion.)

Pair skaters Courtney and Mark have one shot left at their Olympic dream. They vow not to let anything get in their way, especially not Josh and Stephanie, the wealthy and talented brother and sister team. The heart doesn't always listen to reason, though. The more time Courtney spends with sweet, shy Josh, the harder she falls for him.

Dylan Woods hasn’t seen her best friend, Langston, in years. After he moved to Los Angeles, he ghosted her. Then he became Legendary, the biggest teen R&B artist on the planet. For the most part, Dylan has moved on, with her sights set on Juilliard. But when her parents announce that Langston is coming for a short stay with them, the entire family is thrilled. Except for Dylan. The idea of sharing a house with music’s biggest bad boy makes her stomach churn.

Anna is looking forward to her senior year in Atlanta, where she has a great job, a loyal best friend, and a crush on the verge of becoming more. Which is why she is less than thrilled about being shipped off to boarding school in Paris - until she meets Etienne St. Clair: Perfect, Parisian (and English and American, which makes for a swoon-worthy accent), and utterly irresistible. The only problem is that he's taken, and Anna might be, too, if anything comes of her almost-relationship back home.

Stella will do anything for her sick sister, Cara - even stand in line for an autographed Heartbreakers CD for four hours. She's totally winning best birthday gift this year. At least she met a cute boy with soft brown hair and gorgeous blue eyes while getting her caffeine fix. Too bad she'll never see him again. Except Stella's life has suddenly turned into a cheesy love song. Because Starbucks Boy is Oliver Perry, the lead singer for the Heartbreakers.

Molly Barlow isn’t that girl anymore. A business major at her college in Boston, she’s reinvented herself after everything that went down a year ago...after all the people she hurt and the family she tore apart. Slowly, life is getting back to normal. Molly has just said "I love you" to her new boyfriend, Ian, and they are off on a romantic European vacation together, starting with scenic London. But there on a tube platform, the past catches up to her in the form of Gabe, her ex, traveling on his own parallel vacation with new girlfriend Sadie.

If someone had told me a year ago that I was about to fall in love, go on an epic road trip, ride a Triceratops, sing on a bar, and lose my virginity, I would have assumed they were on drugs. Well, that is, until I met Beckham. Beck was mostly to blame for my recklessness.

Jackie does not like surprises. Chaos is the enemy! The best way to get her successful, busy parents to notice her is to be perfect. The perfect look, the perfect grades—the perfect daughter.

Now Jackie must trade in her Type A personality and New York City apartment for a Colorado ranch and all the wild Walter boys who come with it. How can she fit in and move on when she needs to keep her parents' memory alive by living up to the promise of perfect?

Ryn has one unread text message on her phone. And it's been there for almost a year. She hasn't tried to read it. She can't. She won't. Because that one message is the last thing her best friend ever said to her before she died. But as Ryn finds herself trapped in the Denver International Airport on New Year's Eve thanks to a never-ending blizzard on the one-year anniversary of her best friend's death, fate literally runs into her. And his name is Xander.
