this story starts when Annabeth Chase, daughter of athena, rides on the argo II, headed for camp Jupiter. on the argo II rides Jason Grace, Leo Valdez and Piper Mclean. they’re there to retrieve percy jackson from there. when they arrived, leo got possessed by a ghost, and accidentally attacked the camp, and thus caused a war between the roman and the greek demigods. fortunately, they retrieved percy, and two others called frank and hazel. they go on a quest to stop Gaea, mother earth herself, from wakening and destroying the Olympian gods. however, annabeth gets a gift from her mother to retrieve what could be the solution for the roman/greek demigod war. read the book!
i like leo valdez the most, because he’s funny, nice, and he can build a full-functioning nuke with legos.
i once read this book where a god that made life itself wanted more and attacked earth. the characters defeated him, and they were safe.
