The Haunted Halloween of Barnaby Sloan - The Wish Series, #2

Previously published as The Haunted Halloween of Barnaby Sloan by Jenna Jones It's Halloween, and Barnaby and his friends plan to do their usual Halloween ghost walk at a local park that is rumored to be haunted. Barnaby worries his new boyfriend Liam will find their plans ridiculous, and he doesn't even believe in ghosts, but he invites Liam to join them on the ghost walk anyway. While their friends scare each other at the park, Barnaby confides in Liam about why he doesn't believe in an afterlife.
Then Barnaby hears a familiar voice whispering his name -- and of course, he must investigate.
