Ive read this whole series,ALL of the books.I think Riordan should come out with another seires,That has Thesus.These books are the best books ive ever read because it got me inspred to know Almost all of the greek god the names :Zues,Athena,Poseidon,Ares Aphrodite,Hestaphus,Hermes,Apollo,Hades,Artemis.Minor gods:Hecate,Nemisis,Dionysus,Eos And 45 more minor gods.

Read all of the books.It will make alot of sence but lemme tell you one thing.The 5th one is VERY sad.
