Just breathe, Kacey. Ten tiny breaths. Seize them. Feel them. Love them.

Four years ago Kacey Cleary's life imploded when her car was hit by a drunk driver, killing her parents, boyfriend, and best friend. Still haunted by memories of being trapped inside, holding her boyfriend's lifeless hand and listening to her mother take her last breath, Kacey wants to leave her past behind. Armed with two bus tickets, twenty-year-old Kacey and her fifteen-year-old sister, Livie, escape Grand Rapids, Michigan, to start over in Miami. Struggling to make ends meet, Kacey needs to figure out how to get by. But Kacey's not worried. She can handle anything-anything but her mysterious neighbour in apartment 1D.

Trent Emerson has smouldering blue eyes, deep dimples, and he perfectly skates that irresistible line between nice guy and bad boy. Hardened by her tragic past, Kacey is determined to keep everyone at a distance, but their mutual attraction is undeniable and Trent is determined to find a way into Kacey's guarded heart-even if it means that an explosive secret could shatter both their worlds.
