Ten Tiny Breaths series by K.A. Tucker

Kacey Cleary’s whole life imploded four years ago in a drunk-driving accident. Now she’s working hard to bury the pieces left behind—all but one. Her little sister, Livie. Kacey can swallow the constant disapproval from her born-again aunt Darla over her self-destructive lifestyle; she can stop herself from going kick-boxer crazy on Uncle Raymond when he loses the girls’ college funds at a blackjack table. She just needs to keep it together until Livie is no longer a minor, and then they can get the hell out of Grand Rapids, Michigan.

But when Uncle Raymond slides into bed next to Livie one night, Kacey decides it’s time to run. Armed with two bus tickets and dreams of living near the coast, Kacey and Livie start their new lives in a Miami apartment complex, complete with a grumpy landlord, a pervert upstairs, and a neighbor with a stage name perfectly matched to her chosen “profession.” But Kacey’s not worried. She can handle all of them. What she can’t handle is Trent Emerson in apartment 1D.

Kacey doesn’t want to feel. She doesn’t. It’s safer that way. For everyone. But sexy Trent finds a way into her numb heart, reigniting her ability to love again. She starts to believe that maybe she can leave the past where it belongs and start over. Maybe she’s not beyond repair.

But Kacey isn’t the only one who’s broken. Seemingly perfect Trent has an unforgiveable past of his own; one that, when discovered, will shatter Kacey’s newly constructed life and send her back into suffocating darkness.

Livie has always been the stable one of the two Cleary sisters, handling her parents' tragic death and Kacey's self-destructive phase with strength and maturity. But underneath that exterior is a little girl hanging onto the last words her father ever spoke to her. “Make me proud,” he had said. She promised she would...and she’s done her best over the past seven years with every choice, with every word, with every action.

Livie walks into Princeton with a solid plan, and she’s dead set on delivering on it: Rock her classes, set herself up for medical school, and meet a good, respectable guy that she’s going to someday marry. What isn’t part of her plan are Jell-O shots, a lovable, party animal roommate she can’t say ‘no’ to, and Ashton, the gorgeous captain of the men’s rowing team. Definitely him. He’s an arrogant ass who makes Livie’s usually non-existent temper flare and everything she doesn’t want in a guy. Worse, he’s best friends and roommates with Connor, who happens to fits Livie’s criteria perfectly. So why does she keep thinking about Ashton?

As Livie finds herself facing mediocre grades, career aspirations she no longer thinks she can handle, and feelings for Ashton that she shouldn’t have, she’s forced to let go of her last promise to her father and, with it, the only identity that she knows.
