Battle of the beetles

"From a secret Biome in the jungle, Lucretia Cutter plans to wreak wickedness on the world unless Darkus, Virginia, and Bertolt can find a way to stop her. Can Darkus and his friends, human and beetle alike, find it before it's too late? If they fail, she'll amass an army of giant Frankenstein beetles and the planet will never be the same again"--Provided by publisher.
