The three-part Graystripe manga series was announced as the first part of a partnership between Tokyopop and HarperCollins.

[1] Erin Hunter and Dan Jolley would write the stories and James L. Barry would illustrate it.

[8] The cats from the Warriors series live separated as four Clans (called ThunderClan, WindClan, RiverClan, and ShadowClan).

[12] Warrior's Return picks up from the previous volume, with Graystripe and Millie just having found the ruined ThunderClan camp.

The duo leave it behind and find Ravenpaw (a former Clan cat) and Barley, loners introduced earlier in the series.

A review by School Library Journal praised the drawing that "captures the cats' expressive faces, action-packed battle scenes, and familiar surroundings as these animals travel through the realm of the Twolegs and recommended the book for "reluctant readers, manga fans, or "Warriors" enthusiasts".
