Ghostapalooza - Sam the Spectator, #2

2019 B. R. A. G. Medallion Honoree  A ghost-seeing teen goth and her friends confront an evil preacher and an ever-growing mob of spirits in the second book of the Sam the Spectator series - a spooky and humorous supernatural mystery set in 1990s West Texas. There are too many ghosts in Bluebonnet, Texas. No one knows why they've come or when they'll leave but things are starting to get weird: electronics are wonky and the locals are cranky.
Like, scary cranky. If the spirits don't depart soon, the consequences could be catastrophic. Meanwhile, Reverend Lesser and the anti-spectator movement are starting to become not just a nuisance but a threat to Sam and her family. With the help of some unusual visitors - including a hippie, an empath, and several famous spectators, can Sam and the gang figure out what's drawing the ghosts to Bluebonnet in time to save it and themselves?
