Summer Secrets by Jill Sanders

For Hannah Rodgers, running an adult summer camp with her four best friends is the ideal distraction from her controlling family. She’s worked hard to become her own woman, but now her parents want to marry her off for business reasons. What is this, the Middle Ages? Hannah would much rather enjoy the sunny delights of camp and flirt with Owen Costa, the hunky help.
But Owen has his own scheme working behind those beautiful brown eyes: he and his brothers finagled camp jobs with the hope of tracking down their father, an eccentric billionaire prone to sudden disappearances. Though Owen was suspicious of the new camp owners at first, his relationship with Hannah deepens, and he gets waylaid from his mission.
But Owen’s troubles soon resurface, and duty calls him away just as Hannah shares a delicate secret, leaving her shattered. Can they get over their complicated lives long enough to enjoy the romance they both want?
