Sunrise is the sixth and final book in Erin Hunter's Warriors: Power of Three children's fantasy novel series. HarperCollins published it on 21 April 2009. The plot follows Jayfeather, Hollyleaf, and Lionblaze on their quest to find Ashfur's true murderer. It was originally to be titled "Cruel Season", though this was changed because HarperCollins, the series' publisher, felt it was too dark a name.
