Summer at the Shore

This is an Apple Books audiobook narrated by a digital voice based on a human narrator.
Saving lives is who they are 

Risking his life for others is all in a day's work for Coast Guard petty officer Jay Johnston. Until he comes to the rescue of Mia Frasier after her small plane goes down. Maybe it's because the empathetic blue-eyed vet wants to save the world just as passionately as Jay wants to create a safe haven for his five younger siblings, but there's no denying their bond. Despite his growing feelings for Mia, a romantic relationship isn't on Jay's radar. How can two people always on the move stay in one place long enough to create a family of their own?
