Summer Island by Kristin Hannah; 2010. Softcover.

Thirty-four year old Ruby Bridge is a not-too-successful comedienne who uses her mother, a nationally-syndicated "moral and spiritual counselor" as the main fodder for her cynical, rather bitter humor. Her mother Nora, long divorced from Ruby's father, is a woman whose past is just about to catch up with her - in the form of blackmail by a former lover. After an accident (an attempted suicide?) Ruby returns to care for her stricken mother - bitterly resenting the fact that once again her mother's life has colonized hers.

When she is approached by a publisher to write a biography of her mother, Ruby is desperate for the princely sum offered. Yet her research into her mother's past reveals a woman very different from the one Ruby expected. And what began as "mommy dearest" ends as a love story - not only between mother and daughter, but involving two very different men who play a key role in linking the past to the present.
