Betrayal, bad bunnies, and backstabbing galore. Holly Madison's new memoir, Down the Rabbit Hole: Curious Adventures and Cautionary Tales of a Former Playboy Bunny, reveals that life inside Hugh Hefner's Playboy Mansion was not what it seemed.

Us Weekly exclusively reveals the cover of the former Playmate's upcoming book, and shocking aspects from inside her tell-all, in which she details the realities of being one of Hefner's live-in girlfriends.

As revealed in the release from Harper Collins, Madison's seemingly fairy tale existence inside the Playboy Mansion was filled with drama, darkness, and even depression. "Life inside the notorious Mansion wasn’t a dream at all—and quickly became her nightmare," the promotional material states. "After losing her identity, her sense of self-worth, and her hope for the future, Holly found herself sitting alone in a bathtub contemplating suicide."

The publisher also promises to detail the "oppressive routine of strict rules, manipulation, and [her] battles with ambitious, backstabbing bunnies."

Madison, 35, who's now married to Pasquale Rotella and mom to their toddler-aged daughter Rainbow, first skyrocketed to fame in 2005 alongside Bridget Marquardt and Kendra Wilkinson. The trio starred as Hef's girlfriends in E!’s reality series, The Girls Next Door, for five seasons until it ended in 2010.

"I’m excited to finally share my story and what I’ve learned from my personal experiences both inside and outside of the Playboy Mansion," Madison exclusively tells Us "I think my stories will surprise people and I’m looking forward to lifting the veil of mystique and clearing up the misconceptions so often associated with my life."

Her memoir, Down the Rabbit Hole: Curious Adventures and Cautionary Tales of a Former Playboy Bunny, will debut on June 23.
