So. . . you're a fan and have read all of the Percy Jackson books--and The Lost Hero series, and The Kane Chronicles series--and you're looking for something else to read. How about these similar books?
Ghost Leopard by Lars Guignard: This first-in-a-series story is much like The Kane Chronicles but takes place in India and relies on Indian mythology as the backdrop.
Emerald Atlas by John Stephens: This story features 3 siblings, and while it lacks the mythological content of Percy Jackson, it's still close to Riordan's story.
Magyk by Angie Sage: The seventh son of a seventh son disappears the night he is born. . . and a strange baby girl is found in the snow that same night. A great read for Percy Jackson AND Harry Potter fans.
Savvy by Ingrid Law: This has been dubbed "the country bumpkin version of Percy Jackson." The Beaumont kids all get a magical power when they turn 13 years old.
Fablehaven by Brandon Mull: A brother and sister discover their grandparents are caretakers for a preserve of magical/mythical creatures of good and evil.
