THE NIGHTINGALES OF TROY. By Alice Fulton. Norton. 256 pages. $23.95.
Mamie Flynn Garrahan, a mother living in the early 1900s, has earned the nickname Mamie Come Running. If anybody needs help, Mamie is sure to arrive. At 26, she's preparing for the birth of her fifth child. In a more discreet way, she's also preparing for death, hoping her slow decline from a wasting disease doesn't stop her from delivering a healthy baby.
