He’s her good boy gone bad… Rockstar Ryan Waters has always been the responsible one in his band, Warning Sign. The guy who kept an eye on business while chasing his musical dreams with his best friends. And his closest friend lately just happens to be their tour bus driver, Denver Casey. Denver Casey is on the run from her past, and she’s careful to stay within her boundaries. Until Ryan becomes her partner in crime and one by one, those boundaries start to crumble. He’s the exact opposite from the guy she’s tried so desperately to leave behind. Then Ryan turns up missing. And her terror that he’s hurt—or worse—leads to something dark and intoxicating. They both love adrenaline, except this time, the addiction is each other. Falling for her best friend means putting everything on the line, win or lose. But if her hidden past comes back to haunt them, she might also end up risking her life. And Ryan’s.
