Melissa Rivers writes memoir about Joan Rivers

Melissa Rivers has found a way to work through her grief for her mother, sparring partner and closest friend, Joan Rivers.

She's written a memoir.

Crown Archetype announced Wednesday that "The Book of Joan: Tales of Mirth, Mischief, and Manipulation" will come out May 5. According to Crown, an imprint of Penguin Random House, the book will feature jokes, stories and advice. Melissa Rivers said in a statement issued through Crown that laughter had "less side effects than Prozac" and was "a lot cheaper than therapy." She also said that she had written a book she hoped would make her mother laugh.

Joan Rivers died last September after she went into cardiac and respiratory arrest during a throat procedure.
