Flora – Gail Godwin

A 10-year-old (Helen) and a 22-year-old (Flora, a cousin of Helen’s dead mother), spend part of the summer of 1945 together. Helen’s father is working at Oak Ridge on bomb development so Flora is a companion/chaperone. Helen is a precocious, petulant, self-absorbed and incredibly manipulative kid, so interesting character and the ending to the book is a surprise.
