Via our good buddy Florian B, here's news of an August 23rd 2016 release (aka Ray Parks 42nd birthday) that gives a bit more background to Chewbacca's story despite it seems not focusing on Revenge of the Sith.
This complete retelling about Chewbacca comes with a supercool toy Chewbacca head that makes sounds just like a Wookiee!
This full-color, interactive retelling of the Chewbacca story features Chewbacca highlights from A New Hope, The Empire Strikes Back, Return of the Jedi, and The Force Awakens. The collectible Chewbacca toy features a button-activated Wookiee sound that kids will be prompted to start throughout for a feature-rich storytime experience. The front cover is die-cut over the sculpted head to allow Chewbacca to appear on every spread of the book.
