It may not look a day over 39, but Andrew Lloyd Webber’s The Phantom of the Opera is about to turn 40. To mark the occasion, Penguin Random House and LW Entertainment are publishing three new books, set to arrive this fall.

The initiative honors “one of the most enduring and beloved musicals of all time”—seen by more than 160 million people across the world—and aims to “expand the Phantom story across a wide range of publishing categories, engaging longtime fans while inviting a new generation of readers into its world,” the publishers said in a news release.

The first book, Our Strange Duet, will be written by bestselling YA author Erin A. Craig and published by Random House Children’s Books imprint Delacorte Press.

This YA book, written in collaboration with those involved in the production, will focus on protagonist Christine Daaé’s emotional trajectory and give “new depth to [her] experience in the Opéra Populaire, her ambition, her passion, and her love triangle with Raoul and the Angel of Music.”

Craig, whose fantasy novels include House of Salt and Sorrows and The Thirteenth Child, was chosen because of her background in theater, love for Phantom, and “flair for emotionally rich gothic romantasy.”

An audiobook recording featuring a “full cast and enhanced with iconic music from the Phantom musical suite” will be released by Penguin Random House Audio alongside the book.

The second book in the trio is Andrew Lloyd Webber’s The Phantom of the Opera: A Behind-the-Mask Look at the Global Phenomenon, a “celebratory visual anthology” to be published by Ten Speed Press in the U.S. and Ebury Press in the U.K. This coffee-table book will provide an “exclusive behind-the-scenes look at the making and evolution of the iconic global musical…including archival sketches, photography, and interviews with cast, crew, and contributors through the years.”

Penguin Random House Audio will release an audio version of the book as well.

The third title, Phantom of the Opera Little Golden Book by Christy Webster, will “provide the perfect introduction of this timeless love story to young readers.”

Two additional Phantom–themed Little Golden Books are scheduled for publication in 2027.

Our Strange Duet and Phantom of the Opera Little Golden Book are set to be published on Sept. 1. Andrew Lloyd Webber’s The Phantom of the Opera: A Behind-the-Mask Look at the Global Phenomenon will be released on Oct. 27.
