David's 2009 novel "Tigerheart" is a re-imagining of Peter Pan with a mix of new and old characters, told as a Victorian bedtime story, much like the classic tale. It was praised by Ain't It Cool News, and honored by the "School Library Journal" as one of 2008's Best Adult Books for High School Students. His "Sir Apropos of Nothing" fantasy trilogy, "Sir Apropos of Nothing", "The Woad to Wuin" and "Tong Lashing", features characters and settings completely of David's own creation, as does his 2007 fantasy novel, "Darkness of the Light", which is the first in a new trilogy of novels titled "The Hidden Earth". The second installment, "The Highness of the Low", was scheduled to be published in September 2009, but David has related on his blog that it has been delayed until the winter of 2012.
