I found Jake a little hard to like for some reason - he was admirable in his persistence, but I don't know something about him felt a little abrasive.  It was the story about the dragons that kept me hooked.

I was a bit surprised (and confused) the story went further - that it didn't stop when Lois and Dragonhaven was safe.  It totally made sense when Martha and Katie got pregnant.  The whole bonding scene was pretty sweet.
