Years after her Girls Next Door days, the Playboy model opened up about her life at the Playboy Mansion, revealing her years at the iconic home were far less glamorous than they appeared.

“The shocking, never-before-told story of the bizarre world inside the legendary Playboy Mansion – and, finally, the secret truth about the man who holds the key – from one of the few people who truly knows: Hef’s former #1 girlfriend and star of The Girls Next Door," the book's synopsis reads, according to a report by Reality Tea on Monday.

"In this shockingly candid and surprisingly moving memoir, this thoughtful and introspective woman opens up about life inside the Mansion, the drugs, the sex, the abuse, the infamous parties, and her real behind-the-scenes life with Bridget [Marquardt], Kendra [Wilkinson], and, of course, Mr. Playboy himself," the synopsis continues. "With great courage, Holly shares the details of her subsequent troubled relationship, landing her own successful television series, and the hard work of healing, including her turn on Dancing with the Stars. A cautionary tale and a celebration of personal empowerment, Down the Rabbit Hole reminds us of the importance of fighting for our dreams – and finding the life we deserve.”

Since leaving Hefner, and the Mansion, behind, Madison married Pasqualle Rotella, and welcomed her first child, Rainbow Aurora.
