The term is entirely appropriate. As always, I was taped to the beginning of the book at the end of the story. Percy takes us back into a wonderful adventure, fraught with dangers and puzzles (which we say sometimes that is not possible that anyone so fortunate to face them). Cronos is really an important piece of history and we feel coming slowly the outcome of this enigma that is particularly frightening titan. A really good fantasy book I recommend, whether you teenager or not.
