Hi, I searched Bernard Evslin on the forum and did not find any reference, so I want to recommend this author to kids who have read and loved the Percy Jackson books. Evslin has written over 70 books on greek and other myths, but mainly greek. The ones I've seen range from 6th-9th grade reading levels. We just found a pile of these at the library and ds9 is delighted! There is a 'Monsters of Mythology' series which seems to have 25 books in it, so that should hold him for a while.
