In this one, a very imaginative boy has claimed to find a gun - a BIG gun with a monster on it. The town dismisses him - kind of like the "boy who cried wolf". But when he turns up dead the next day, they know they seriously missed something. The race is on to find the killer, but everything else that would be uncovered in the meantime left chills running down my back.

The most fascinating thing to me is how Penny manages to maintain so much familiarity from one book to the other (the characters, the scenes, etc), yet also keeps the series so fresh and new. Little details are added along the way, and what happens is that the reader becomes so fully invested, these people and places feel very real.
