Diamonds, Teak, and Murder by A. M. Ialacci

Upon the sudden deaths of her parents in a car accident, credit fraud investigator Allie Fox traded her fast-paced life in Chicago for a boatyard bookkeeping job in sleepy Carteret County, North Carolina. It is a huge transition, especially as she is now the sole caregiver for her younger autistic brother. But when the yard foreman mysteriously ends up dead at work, she can’t resist being pulled into the mystery.

The deeper she digs, the more secrets she unravels, and the killer turns his sights on her, and even worse, her brother.
