Late Nights by Larissa Hommes

They say there’s no place like home, but what do you do when the person you’ve been trying so hard not to fall for becomes your roommate?
Cannon James believes in keeping everyone at a distance, especially in matters of the heart. His commitment to the bachelor lifestyle has served him well, until his best friend’s little sister, Demi Vanderhall, unexpectedly appears on his doorstep in need of a place to stay.
Despite knowing each other for a decade, Cannon has never confessed to anyone that Demi is the one girl he struggles to keep at arm’s length. With her brother’s disapproval looming and Cannon’s own tumultuous past lurking in the shadows, he’s determined to resist any romantic relationship.
Yet, as late nights spent together deepen their connection and test their self-restraint, Demi begins to question why they shouldn’t explore the possibility of more than just friendship. But every time they edge closer to crossing that line, Cannon slams on the brakes, haunted by his past and unable to fully embrace the future.

Can Demi break through Cannon’s walls and convince him to take a chance on them? Or will the ghosts of his past forever hold him back from finding true happiness?
