With this latest addition to the "Dog Days" series, I am officially a fan. "Unleashed" is my favorite so far. Levitt did a great job of building suspense, creating vivid images of the paranormal, and keeping the reader guessing.
The second book in the series, "New Tricks", was fine, but did not grab me as much as the first book, "Dog Days." "Unleashed" just seems more put together as a story and is definitely more creepy. I wish I could comment in more detail, but I don't want to give anything away--however I was glad to see some characters from earlier in the series back and I am interested in seeing what Levitt does with them in future editions.
There is one issue in this novel that the author addresses, but ultimatley leaves unanswered. I suspect it will be part of the next book, and I am looking forward to seeing how it is handled. I can say I was pleased how this story ended.
If you are a fan of Butcher's "Harry Dresden" or Brigg's "Mercy Thompson" series, you will probably enjoy Levitt's stories.
