The manga was published by the distributor Tokyopop, and was released on 26 December 2007 along with Dark River, the second book in Warriors: Power of Three.

Coming to the current time, Graystripe and his traveling companion, Millie, can see Highstones in the distance.

Over time, the Twolegs accept the barn cats as well and even adopt them as their kittypets through a plan of Graystripe's.

HarperCollins and Tokyopop had agreed to publish a trilogy of Graystripe manga volumes, announced in February 2007.

[1] It was released on the same day as Dark River, the second book in the Warriors: Power of Three series.

[1] School Library Journal gave the book a mixed review praising "Millie's bravery", but also criticizing how scratchy text used when humans talk seems very odd when used with the toddlers.

The review also criticized how the "artwork is merely competent and the story (which was not written by Hunter) is slight".
