I have read (listened to) most of the Riordan books with Greek and Roman gods, and I really have enjoyed most of them. My younger son (currently 14, but 13 for most of them) has listened with me, and he found them enjoyable. Furthermore, they touch on the mythology of the Greek and Roman gods, and the amount of knowledge gained, just in those areas, has been significant. This particular book, focused on Poseidon, is quite different from Percy Jackson and the sea of monsters, the both of them were good.
