Amateur ghost expert Eliza, thirteen, joins her botanist mother on a job in a very old flower shop, where each investigates some highly unusual things.

"It's prom season, which means the Bloom family's flower shop should be busier than ever. Instead, they can't seem to sell a single corsage! Del is pretty sure that the fancy rival florist in town is to blame. Too bad the owner's son is Hamilton, the cute new boy in Del's class. To make matters worse, the big school dance is coming up, and Del's best friend, Becky, has been acting super-weird about it."--P. [4] of cover.
