Any suggestions for my DD10? She's into Greek mythology and has read the Percy Jackson series more times than I can count. She also liked the Myth-o-Mania series, although the books are so short that she flew through them. DD can read at pretty much any level, but prefers books in the 6th-8th grade interest range. I have Heroes, Gods and Monsters of the Greek Myths on my library waiting list, but I'm looking for more ideas.
