USA Today bestselling author Rachel Grant also writes thrillers as R.S. Grant. She worked for over a decade as a professional archaeologist and mines her experiences for storylines and settings, which are as diverse as excavating a cemetery underneath an historic art museum in San Francisco, survey and excavation of many prehistoric Native American sites in the Pacific Northwest, researching an historic concrete house in Virginia (inspiration for her debut novel, CONCRETE EVIDENCE), and mapping a seventeenth century Spanish and Dutch fort on the island of Sint Maarten in the Caribbean (which provided inspiration for the island and fort described in CRASH SITE).She lives in the Pacific Northwest with her archaeologist husband and demanding cat.
