I'll let you in on a little secret: I mostly read these books for the mice. The Aeslin are awesome!
I find this series such a relaxing read, that I'm always looking forward to reading it and enjoy it, even though I think this was not the best in the series. One of the main attractions is the world filled with all the fantastic beasts so I was a little bit disappointed that it's mainly werewolves here. I mean, been there, done that. (Instead give me some more Aeslin please) Also I think Australia would have been perfect to create new species of cryptids that were not yet introduced to us before.
Either way, it was still an enjoyable adventure, although not that special. I'm still looking forward to more Alex in a later book, as I like his scientific approach.
