A Ghostly Trickster

Sam Sanchez is once again testing his abilities to help ghosts cross over to their afterlife. This time, he meets his friends, Rocky, Eliza, and Libby at a camp in Maine where they've volunteered to help reopen a scenic trail. But multiple pranks, aimed mostly at Sam, make it hard to concentrate on why a young ghost named Daniel is trapped on Earth.
Soon the fun pranks turn into more dangerous tricks, and ominous voices in the woods make them realize that someone, or something, doesn't want the trail reopened. Is it pirate ghosts, guarding their treasure? Or evil spirits protecting their sacred land? As Sam and his friends work to finish the trail, a deadly turn of events puts them face to face with an angry ghost who threatens their ability to help Daniel-as well as their ability to survive.
