I really liked this. I was surprised to find out after I finished it that it was written by a thirteen year old. The writing was spectacular when you take that into consideration (you should read some of the garbage I wrote at 13--on the second thought, don't). It reminded me a bit of something Anne Rice might have written at thirteen. 
 I rated it three stars because it was so short, and I feel like the author could have done much more with it if it had been longer. But I enjoyed it and really liked the characters. I would have liked to have seen her done more with them. I particularly liked the flashback scenes. I look forward to continuing with the Den of Shadows quartet. Luckily I have a bind-up of the books and can move right on to the next one. 
 Bonus points because most of it was set in Massachusetts, which is where I live.
