Perfection: a memoir of betrayal and renewal by Julie Metz

Although this book is in the fiction collection, the author says she's only changed others' names and the order of some of the events.
Imagine the shock and grief at having your husband suddenly die; but add to that the discovery that he had numerous affairs during your marriage. This book recounts how the author deals with this, while continuing to raise their young daughter. It reads as an honest portrayal of a woman attempting to hold it all together though ready to break apart.
