Melissa Rivers has penned a tribute book to her mother Joan Rivers, where she reminisces "in our family we always believed that laughter was the best medicine."

Joan Rivers died of brain damage in early September 2014 caused by a loss of oxygen that she suffered while undergoing a routine outpatient throat procedure.

In "The Book of Joan: Tales of Mirth, Mischief and Manipulation," People Magazine reports her daughter reflects "I wanted to write a book that would make my mother laugh.

"I hope it makes you laugh, too," Melissa Rivers continues in the book.

Published by Crown Archetype, editors are trumpeting Melissa Rivers' words as "funny, poignant and irreverent observations, thoughts and takes about a woman who raised her."

The book is slated to hit stores on May 5, and will feature such personal anecdotes as the time Joan Rivers' parents delivered her as a birthday gift to late night talk show king Johnny Carson when she was just nine months old.

Melissa Rivers recently filed a multi-million dollar wrongful death suit in connection with her mother's death, stating physicians were so occupied "taking cell phone pictures of their famous patient" they neglected administering the medical treatment that she needed. According to the New York Daily News, for 17 minutes Joan Rivers' blood pressure, heart rate and oxygen levels were allowed to perilously drop after doctors failed to make certain oxygen was being allowed to her brain.

The suit further alleges doctors ignored the concerns of the acting anesthesiologist, who urged added caution after detecting "incredible edema," or swelling, in the patient's throat.

"You're being paranoid," the suit states one of the doctors admonished anesthesiologist Renuka Bankulla. "You're such a curious cat. You always need to see everything."

The suit also charges that for nearly half-hour doctors tried to revive Rivers without so much as performing a tracheotomy that could have opened up her airways

"Had the doctors acted as physicians for Joan Rivers instead of groupies, Joan Rivers would have been doing 'Fashion Police' last week," said family attorney Jeffrey Bloom.
