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."
