Lenny Kravitz is writing an autobiography covering the first 25 years of his life, and it will be released this fall.

Announcing the news on Instagram, the Grammy Award-winning singer said the memoir will be out on October 6.

The book, titled “Let Love Rule,” is jointly written by Kravitz and biographer and songwriter David Ritz.

“Writing this memoir has been a beautiful and interesting experience taking me through the first 25 years of my life, from birth to release of my first album,” Kravitz said in a statement.

He added, “That journey, full of adventure, was where I found myself and my voice. Through that experience, love was the force that paved the way and love became my message.”

According to a press release, the book is “the story of a wildly creative kid who, despite tough struggles at school and extreme tension at home, finds salvation in music. In one lightning-fast chapter after another, we see him grow as a musician and ultimately a master songwriter, producer and performer. We also see Lenny’s spiritual growth – and the powerful way in which spirit informs his music.”
