Tess Gerritsen left a successful medical practice to bring up her children and concentrate on her writing. Her two previous highly acclaimed novels, Harvest and Life Support, were both New York Times bestsellers. She lives in Maine, with her family, and in her free time plays fiddle with the Tattered Tartans.
