When a series of passenger airplanes crashed in Elizabeth, N.J., within a three-month period in 1951-1952, Judy Blume was a teenager. "These events have lingered in my mind ever since, " says Blume. Against this background, Blume uses her imagination to bring us the lives of three generations of families, friends, and strangers who will be profoundly affected by these events, either directly or indirectly. This is Blume's first novel for adults since "Summer Sisters."
