Spook Squad

Let me start by saying this is a wonderful series, and has been an absolute pleasure to read the past few days. I have been eating these books up! However, Spook Squad was my least favorite (even though it's still good) for a couple of reasons. It was great until I figured out the big mystery less than halfway through the book and spent the rest of the time frustrated that everyone was still clueless. I also figured out the 2nd surprise ahead of time so there wasn't much to look forward to. The ending left me feeling disappointed as well, but I still love all the characters and love their adventures and will eagerly await the next book in the series.
