I’ve done a bit of digging on this, and I think 'Boozoo’s Ghost' is entirely a work of fiction. The author, Z. G. Zatkin, seems to specialize in those kind of spooky-but-not-too-scary middle grade adventures. There aren’t any direct citations of real-life legends in the text, from what I recall. The haunting involves a poltergeist obsessed with jellybeans and making furniture float, which feels more like a playful invention than something lifted from folklore.
That said, the vibe of the old, inherited house in the Louisiana bayou does pull from a general atmosphere of Southern Gothic ghost stories. It’s not based on one specific tale, but the setting taps into that rich cultural backdrop of creaky plantations and humid, mysterious nights. The book’s strength is how it creates its own memorable mythology around Boozoo, rather than retelling existing ones. I finished it feeling like I’d met a new ghost, not an old one.
