Frasier Island — Susan Page Davis

After specialized underwater training, Ensign Rachel Whitney is posted to a remote island in the North Pacific, a tiny scrap of rock guarding a highly classified secret. She could love her new assignment if her commanding officer, Lt. George Hudson, weren't so obstinate--and a bit distrustful.

Despite George's first reaction to her presence on the island, Rachel sets out to prove she is perfect for the job. She doesn't dream of being a heroine or falling in love, but months later, when word leaks out about the prize they are guarding, Rachel and George have few resources besides each other and their faith in God to foil an enemy attack that could endanger all of America.
