Half Moon Whim by Erin Brockus

Sara and Jack… Will her searing flame scorch him to the bone?
Sara Collins never wanted to put down roots. When her sister offers her a job at the sunny Caribbean scuba diving resort she owns, Sara jumps at the chance to manage her own spa. Even if it means interacting with the divemaster who humiliated her.
Jack Powell is finding his dream life more challenging than expected. Especially after his boss’s sister moves to town—they don’t exactly get along. He tries to avoid the situation, which is difficult when he can’t stop thinking about her.
Throw in a handsome, successful developer who offers Sara everything she ever dreamed of, and she finds St. Croix might be exactly what she’s always wanted. But which man holds the key to her heart and her greatest dream?
