Former romance author and medical doctor Tess Gerritsen is writing in a new genre: medical suspense. Advertised as her "first novel," Harvest jumped onto the New York Times bestseller list and thus legions of new fans were introduced to the work of this talented author. Gerritsen's second thriller, Life Support, is as moving as any of her romances. Dr. Toby Harper works the night shift in an emergency room. More comfortable with the steady horror and tedium of emergency care than with a normal lifestyle, Toby alienates herself socially from her peers and from her sister. She spends her daytime hours alone with her mother who suffers from Alzheimer's disease. When elderly Alzheimer's patients from the same retirement home start dying mysteriously, Toby is the only one suspicious enough to investigate. As a result she finds herself, her mother, and her own sanity at risk.
