From the publisher:

Legendary comic book creator John Byrne returns to the title he first drew 50 years ago, Uncanny X-Men, with this one-of-a-kind new graphic novel trilogy, X-Men: Elsewhen. This three-volume graphic novel series picks up the story from Byrne's original run, taking the characters in new and unexpected directions.

In Volume 1 of X-Men: Elsewhen, a national bestseller, the Dark Phoenix Saga is over and Phoenix is . . . alive?!

Diverging from the epic finale of the original storyline from 1984, X-Men: Elsewhen presents a universe where Jean Grey's powers and intellect have been greatly reduced, and from there, everything you thought you know about the X-Men is forever changed.

John Byrne's monumental return to the X-Men heads in entirely new and surprising directions, as the X-Men head back to the Savage Land, face their climactic adventure with the Sentinels, and contend with special guest–stars such as the Avengers and the Fantastic Four along the way.

X-Men: Elsewhen is a three-volume graphic novel series in the Marvel Arts line that sees the return of acclaimed X-Men artist Byrne decades after his last work on the series. Byrne has written and penciled every page and inked multiple chapters, all of which pick up the story from where his first go–round ended, taking this beloved lineup of characters—and his fans—in exciting new directions.
