Off the Bookshelf: POSEIDON'S ACADEMY, by Sarah Vogler

In this fantasy world and adventure series, the Greek gods were destroyed when mortals rebelled. Their powers remained, however, and were spread throughout the world, so mortals have them now. They are labeled according to the god who had them first: Poseidons, Demeters, Sirens, etc.

Of course, there's a prophecy that they will return ...

Hailey and her friends manage to get accepted at Poseidon's Academy, an underwater school built in Poseidon's palace. For Hailey, the big attraction is that she'll be cut off from the sky, because that is the source of her power. Hailey is a Zeus, and she doesn't like being a Zeus -- and not just because the prophecy seems to expect her to mess up and bring back the gods.

Not all the mythological creatures are dead and gone, and some of them want to bring back the gods.  When some of the students break rules and go out of bounds, they run into those creatures. Hailey and her friends come close to getting expelled a few times. Then there are problems they have to deal with, coming from some of the "mean girls" at school -- who happen to have the powers of Aphrodite and the Sirens, for instance.

I'm reminded of the statement in The Incredibles: "When everyone is super, then nobody will be." That's not exactly how it works out here, but there are drawbacks to everyone having some kind of talent, with all the accompanying in-fighting and jealousy. Some powers are still better than others, and some people should never be given powers. Hailey and her friends survive their first year at Poseidon's Academy. I can only imagine what problems they'll have to deal with in their second year.
