Shay Tanner has three rules when it comes to her acting career: Rule #1: No dating costars. Rule #2: Don't compromise your morals for a role. Rule #3: Never break rule #1. Ex-musician Dustin Shaw threatens each of them just by breathing. Not only is he brooding, reclusive, and undeniably attractive, but he's her best friend's roommate. Now Shay's roommate while she's in town filming for the role of a lifetime. Everything would have been fine if he hadn't unintentionally stolen her costar's part. Dustin Shaw has been in a slump since his band broke up five years ago and now spends his days writing songs for washed-up performers. Lately, though, he can't seem to put a single thought into words. When he's cast in an upcoming movie, his agent thinks it might be what he needs to spark his creativity. Except, the role is for the love interest of his new roommate, and staying away from her is difficult enough without having to kiss her on screen. All it takes is a few minor interactions to make Shay question her resolve and leave Dustin fantasizing about all the ways he'd like to break her number one rule. That Girl & This Guitar is the enchanting first book in the Lonely Melodies contemporary romance series.
