Dannie Kohan lives her life by the numbers. She is nothing like her lifelong best friend - the wild, whimsical, believes-in-fate Bella.

But when she awakens, she’s suddenly in a different apartment, with a different ring on her finger, and beside a very different man.

Katy has been waiting years for Carol to take her, and now she is faced with embarking on the adventure alone.

To the Green-Eyed Lovebird: We met 15 years ago, almost to the day, when I moved my stuff into the NYU dorm room next to yours at Senior House. You called us fast friends. I like to think it was more. We lived on nothing but the excitement of finding ourselves through music (you were obsessed with Jeff Buckley), photography (I couldn’t stop taking pictures of you), hanging out in Washington Square Park, and all the weird things we did to make money. I learned more about myself that year than any other. Yet, somehow, it all fell apart.

They say you can never go home again, and for Persephone Fraser, ever since she made the biggest mistake of her life a decade ago, that has felt too true.

Until the day her secret letters are mailed, and suddenly, Lara Jean’s love life goes from imaginary to out of control.

The only catch: Josh wants a big family.

Finding a good roommate through a classified ad isn’t as easy as it sounds. I was starting to lose hope. Until a knock at my door came, and God answered my prayers. Except...uh...wrong prayer, God. I’d definitely requested the big guy find me a drop-dead gorgeous man on more than one occasion...just not as my roommate. Declan Tate talked me into interviewing him anyway.

Ramona was only five years old when Hurricane Katrina changed her life forever. Since then it's been Ramona and her family against the world.

Alice had her whole summer planned. Nonstop all-you-can-eat buffets while marathoning her favorite TV shows (best friends totally included) with the smallest dash of adulting - working at the library to pay her share of the rent.

Alice is done with dating - no thank you, do not pass go, stick a fork in her, done. But then Alice meets Takumi and she can't stop thinking about him or the rom com-grade romance feels she did not ask for.

The last time Lex was happy, it was before. When she had a family that was whole. A boyfriend she loved. Friends who didn't look at her like she might break down at any moment. Now she's just the girl whose brother killed himself. And it feels like that's all she'll ever be. As Lex starts to put her life back together, she tries to block out what happened the night Tyler died.

Two secrets. One bet. Who will break first? Taylor Caldwell can't decide if she wants to kiss her new college roommate or punch him.

Best friends Dave and Julia were determined never to be cliché high school kids. They even wrote their own Never List of everything they vowed they'd never, ever do in high school. Some of the rules have been easy to follow, like number five, never dye your hair a color of the rainbow, or number seven, never hook up with a teacher. But Dave has a secret: he's broken rule number eight, never pine silently after someone for the entirety of high school. It's either that or break rule number ten, never date your best friend.
