Sometime Around Midnight by Anne Berkeley

Mattie Whalen had her life mapped out from the tender age of…hell, too young to remember. It was simple. Earn her teaching degree. Win the heart of Hautboy bassist, Carter Strickland. Bear his children. Travel the world at his side. When her plans go awry due to her brother’s interference, she’s accomplished two of her goals. Winning his heart excluded.
Carter Strickland has one regret in life, and it isn’t having slept with his bandmate’s little sister, it’s having let her go. But he isn’t about to let a moment of panic or her brother Jake stand between them. Not again.
When Mattie returns home from college with boyfriend Haris Kovač, is Carter too late? Has she already moved on?
One thing for certain, neither man is letting her go without a fight.
