“The Beautiful Ones,” a memoir that Prince started not long before his death in 2016, will be released in October as a “newly envisioned” book featuring rare photographs and handwritten lyrics, the publisher Random House announced on Monday.

Famously private and often inscrutable, the singer, who died of an accidental opioid overdose at the age of 57, had announced the project just weeks before he was found dead at his Paisley Park estate in Chanhassen, Minn.

“We’re starting right at the beginning — my first memory — and hopefully we can move all the way to the Super Bowl,” Prince, who played the halftime show in 2007, told a small crowd at a mini-concert to celebrate news of the book in March 2016.

“The good people of Random House have made me an offer that I can’t refuse,” he added. “You all still read books, right?”
