Keith Richards is writing a children’s book. Per Billboard, Gus & Me: The Story of My Granddad and My First Guitar, which remembers Richards’ relationship with his beloved grandfather Gus Dupree, will be released this fall with illustrations by Richards’ daughter Theodora Richards. Barnaby Harris and Bill Shapiro are assisting Richards with the writing. This all might seem insane coming from Keith Richards, whose last book, the memoir Life, included accounts of rampant drug abuse, threatening a party guests with a sword, and sleeping with Marianne Faithful while she was dating Mick Jagger. But Richards already has five grandchildren*, so the legendarily hard-living Rolling Stones guitarist might actually know more about kid stuff than you think.

Gus & Me: The Story of My Granddad and My First Guitar is due out this fall via Little, Brown Books for Young Readers.

*An earlier version of this post stated that Richards is about to become a great-grandfather. That is not true. Mick Jagger is about to become a great-grandfather; his granddaughter Assisi Jackson is due to give birth next month.
