Melissa Rivers Writes Loving, Funny Tribute to Her Mother, The Book of Joan

"I wanted to write a book that would make my mother laugh. I hope it makes you laugh, too," she says

When Joan Rivers passed away in September, Melissa Rivers said in a statement she knew her mother's final wish "would be that we return to laughing soon."

Since then, Melissa has found comfort in writing about the loving, hilarious relationship she had with with the beloved comedy icon. On Tuesday, she announced she's penned a tribute book for her mother called, The Book of Joan: Tales of Mirth, Mischief and Manipulation.

"In our family, we always believed that laughter was the best medicine," Melissa said. "Not only are there less side effects than Prozac but it's a lot cheaper than therapy. I wanted to write a book that would make my mother laugh. I hope it makes you laugh, too."

Melissa "will share funny, poignant and irreverent observations, thoughts, and tales about the woman who raised her and is the reason she considers Valium one of the four basic food groups," reads a press release for The Book of Joan. She'll also share stories (like when, at nine months old, Joan gifted her to Johnny Carson for his birthday), life lessons (get ready!), math tips ("I can do tips and discounts and figure out the number of gay men in an audience to make it a good show. That's all the math you'll ever need") and more from what it was like to belong to a family Melissa "describes as more Addams than Cleaver."

The Book of Joan is scheduled for a May 5, 2015 release.
