All right Stephen King fans, you’re getting a serious piece of Easter Eggery this fall. One Beryl Evans, known in the The Waste Lands (the third book in the Dark Tower series) as the author of Charlie the Choo-Choo, has apparently popped over to our dimension long enough to write us our own version of the children’s tale!

Simon and Schuster released details on the book, saying:

Fans of Stephen King’s The Dark Tower will definitely want this picture book about a train engine and his devoted engineer. Engineer Bob has a secret: His train engine, Charlie the Choo-Choo, is alive…and also his best friend. From celebrated author Beryl Evans and illustrator Ned Dameron comes a story about friendship, loyalty, and hard work.

Readers of the Dark Tower will recall that while Charlie is a fictional character in the book that Jake buys in the Manhattan Restaurant of the Mind, he may also be alive and living in Gage Park. He also made an appearance in Stephen King’s The Cell. Beryl Evans already appeared before a packed crowd at San Diego Comic-Con last July…sort of. The new book will also feature illustrations by Ned Dameron, who is completely 100% real, and from our own current dimension.

And what of Beryl’s friend, Stephen King? He blurbed the book, saying, “If I were ever to write a children’s book, it would be just like this!”

Wait a minute….

You can get your own copy of Charlie the Choo-Choo on November 22nd (no guarantees it’ll lead you to a gunslinger, though) and prepare yourself for The Dark Tower when it hits theaters next February.
