Thank you to NetGalley for providing a review copy. 

I had such a great time with Helloween! This book has a LOT going on and is an absolute brick, but the plot never gets bogged down and the story moves along at the perfect clip. When a story has this many .moving parts and a large cast of characters, I sometimes have issues remembering who the characters are. Ralston managed to make his characters memorable enough that I was able to both remember them and the plot points they were involved with. 4.5 stars
