I'm a well read grad student who's bluntly honest about all things, although I try to be most honest about myself.
This was hobbled a bit by having to take in really disparate threads from the first two novels. However, it didn't fall into the trap of the second novel, and seemed far less disjointed. Part of this is although it employs some of the same techniques, it limits itself a bit more. In Another Pan, you were bombarded with thoughts from the whole cast; in this one, the journal entries are limited to Thomas.
It does a fairly good job of tying everything together. An excellent job if not for the feeling that it was a bit forced. Again, it's the feeling that the authors were stretching a bit to take so much different mythology and shove it all together.
That being said, I was pleased with this novel. I'd been hoping for more of a four star, for it to drop the disjointedness completely, and while some of that sensation crept back in, it wasn't as bad as it was in Another Pan.
I just came back from a perfect morning at the beach and my brain is a bit fried, though, so sorry this isn't longer or more of an analysis of the book.
