The Lightening Thief by Rick Riordan. Also pinning this for all five books in the series. Read these in third grade and, again, I still pick them up and love them. The movie, however, was not that great. I think they made Annabeth's hair blonde at least in the second movie .... Also not a fan of the continuement of this series with The Lost Hero. But I love Percy Jackson.
