The Longest Halloween Book Two oleh Frank Wood

In book two of the series, our hero Joel Franklin and his cohorts find themselves on a supernatural scavenger hunt for an age old amulet with incredible kingdom building power. Joel, on-again, off-again girlfriend Polly, brother Jasper and best friend Ellis courageously outwit nineteenth century pirates, a disgraced witch and her den of vicious werewolves and a gang of hapless, want to be bandits led by the strangest substitute teacher this side of the Atlantic Ocean. In an exciting and fast- paced race unfolding over three days prior to Halloween, Joel and his intrepid friends learn that true power comes not from what you own but from what you are willing to sacrifice.
