Haha hi!!! Yea I heard A LOT of controversy on the book -- it was either hated or loved. I, personally, have things for hot Italian looking mythological creatures, so I was kind of drawn towards the book and Galen! Not to mention that I am unhealthily obsessed with anything to do with Greek/Roman mythology, especially Poseidon, so anything with that in the title -- I'm a goner!
Yeah, it's really great, not as much mythology as I expected, but the realm is very easy to immerse yourself in, and to love. I think you should definitely read it if you like mythology though, because it's just got that feeling, and for the sad lack of good mythology books that keep to the true myths, I'd rather read a book that doesn't pretend to be greek mythology than one that does.
