Molly Barlow is facing one long, hot summer - 99 days - with the boy whose heart she broke and the boy she broke it for...his brother. Day 1: Julia Donnelly eggs my house my first night back in Star Lake, and that's how I know everyone still remembers everything. She has every right to hate me, of course: I broke Patrick Donnelly's heart the night everything happened with his brother, Gabe. Now I'm serving out my summer like a jail sentence: Just 99 days till I can leave for college and be done.

Former child actor Fiona St. James dropped out of the spotlight after a spectacularly public crash and burn. The tabloids called her crazy and self-destructive and said she’d lost her mind. Now in her late twenties, Fiona believes her humiliating past is firmly behind her. She’s finally regained a modicum of privacy, and she won’t let anything—or anyone—mess it up.

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.

It all started with an unexpected phone call. Two years after my fiancé passed away in an accident, his father died suddenly, leaving Brad’s adult special-needs brother with no one to care for him. The next thing I knew, I was on a cross-country drive to New Hampshire where I’d be moving in to look after Scottie until I could get him into a group home. The last thing I ever expected? I wouldn’t be taking care of him alone.

After failing my last semester of grad school, I decided to come back to my hometown and wallow in my boyfriend’s sympathetic arms. Instead, he proceeded to dump me...for being boring! Now, I'm not typically a spiteful person, but there's only so much I can take. Hence why I’m holding the box of his most cherished possessions...stolen possessions no less!

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.)

I didn’t know bridesmaid was code for babysitter for the bride’s brother, but if that’s what my best friend needs of me for her dream wedding to go off without a hitch, that’s what I’ll do. Even if Theo Monroe has been a pain in my rear since third grade. Even if he should be responsible enough to not wreak havoc at his sister’s destination wedding.

When my grandmother found out she didn’t have long to live, she embarked on a crazy trip—jumping out of airplanes and scuba diving with sharks. After I repeatedly voiced my concern, Gram blocked me—her own grandson—on text and social media, leaving me only her travel companion Eleanor’s number.

Meanwhile, in New York City, Dean Tenney, former Major League pitcher and Andy’s childhood best friend, is wrestling with what miserable athletes living out their worst nightmares call the "yips": he can’t throw straight anymore, and, even worse, he can’t figure out why.

Growing up, the three of us were friends. He was the nerd. I was the playboy. She was the beauty. Deep down, I only ever wanted her.
