There's not much to say about The Coming of Hoole. It continues the legends that started unraveling in The First Collier, but it shifts the focus from Grank to Hoole. I like the inclusion of the polar bears (at this point, I like the inclusion of any non-owl creatures that get treated with basic respect), and I don't dislike the characters of Hoole or Theo, though Theo seems fairly extraneous.
The mythology is still garbled (I've given up on "What the hell are hagsfiends?" and moved on to "What the hell are halfhags?", which is even more confusing.), but there's a small victory in that the term Ga' is finally explained upon its hundredth use. Apparently, Ga' means "great spirit; a spirit that somehow contains not just all that is noble, but all that is humble as well".
All in all, I have to give this another two star rating. Parts of the story definitely deserved a three, but a lot of it was positively wince-worthy. At this point, I'm just looking forward to this series being over.
