Gruber's Happy Halloween (Gruber and Sampson's Unordinary Life Book 1)

Gruber and his monkey Sampson have been invited to their first Halloween party! It's exciting, and they dream of all the costumes they can wear to the big day...

There's only one problem though. Everything they can think of to wear terrifies them! They decide to go as themselves, which would be fine, if the party weren't being thrown by a group of Vampires!
