Eternity's Wheel was issued by HarperTeen, an imprint of HarperCollins Publishers, on May 19, 2015.

In a YouTube posting from April 2013, Gaiman explained that he met up with Reaves and Reaves (who are father and daughter) to plot out the third volume of the trilogy, but as with the previous volume in the InterWorld series, Gaiman's commitment to other projects prevented him from doing actual writing work on the book.

The elder Reaves, meanwhile, suffers from Parkinson's disease, and was therefore unable to actually perform much (if any) writing work.

Consequently, Eternity's Wheel was essentially written in its entirety by Mallory Reaves, with story notes and editing advice from the two credited co-authors.
