Kennedy Kay is the only woman on the medical staff for Chicago's professional baseball team. With her dream job within reach, she's determined to keep her reputation spotless during her final season. But after a wild night in Las Vegas, she wakes up with a hazy memory, a wedding ring on her finger, and an unexpected husband.
That husband is Isaiah Rhodes, the team's charismatic shortstop, who has secretly been in love with Kennedy for years. To protect her career, they agree to pretend their impulsive Vegas marriage was intentional and stay married for the rest of the baseball season.
What begins as a fake relationship and marriage of convenience soon turns into something much more real as Isaiah sets out to prove he's the perfect husband—and Kennedy discovers that the one thing she never planned for might be exactly what she needs.
