Misunderstood and overprescribed, twelve-year-old Lilith Bloom finds the prospect of a grand family reunion decidedly dull... That is, until she discovers that the rose garden surrounding her grandfather's Berlin mansion is, well, completely and utterly carnivorous. Armed with Panther, her talking pet whippet, and the help of the mute boy next door, Lilith must unravel the secrets behind the mysterious estate, all while her family remains gloriously unaware that they are about to be devoured.
