Hayden Panettiere's 320-page tell-all memoir will be published by Grand Central Publishing on May 19, 2026. She spent two years writing it, calling it the hardest thing she has ever done.

The memoir prompted her public bisexual revelation. She said writing forced her to confront truths she had hidden for decades, including her attraction to women since childhood.

The book details her battles with postpartum depression after the birth of her daughter Kaya, her addiction and path to recovery, and the domestic abuse she endured.

Panettiere opens up about her relationships with Heroes co-star Milo Ventimiglia and her former fiance, boxing champion Wladimir Klitschko, father of her daughter.
