Philip Yates lives in Austin, TX, and works in the Austin Public Library system. A Pirate's Night Before Christmas was his first picture book. It was so successful he created a sequel, A Pirate's Twelve Days of Christmas, which received praise from the Horn Book (“The pirate lingo and raucously detailed color-rich illustrations add seafaring flair to this holiday standard”) and Kirkus Reviews (“Avast, me hearties! Here be another bonny piratical parody ready for the readin' to the young'uns at the Christmas season.”)
