Wicked Bugs (Young Readers Edition): The Meanest, Deadliest, Grossest Bugs on Earth
by Amy Stewart Briony Morrow-CribbsDid you know there are zombie bugs that not only eat other bugs but also inhabit and control their bodies? There’s even a wasp that delivers a perfectly-placed sting in a cockroach’s brain and then leads the roach around by its antennae — like a dog on a leash. Scorpions glow in ultraviolet light. Lots of bugs dine on corpses. And if you want to know how much it hurts to get stung by a bullet ant (hint: it really, really hurts), you can consult the Schmidt Sting Pain Index. It ranks the pain produced by ants and other stinging creatures. How does it work? Dr. Schmidt, the scientist who created it, voluntarily subjected himself to the stings of 150 species. Organized into thematic categories (Everyday Dangers, Unwelcome Invaders, Destructive Pests, and Terrible Threats) and featuring full-color illustrations by Briony Morrow-Cribbs, Wicked Bugs is an educational and creepy-cool guide to the worst of the worst of insects, arachnids, and other arthropods. This is the young readers adaptation of Amy Stewart’s bestselling book for adult readers.

Wicked Nix
by Lena CoakleyNix starts out as the whimsical story of a woodland fairy who is up to no good but has the best of intentions. He brings to mind Puck from A Midsummer Night’s Dream—he is wonderfully awful and charmingly mischievous, and, for some reason, we know we won’t be able to resist delighting in his misdoings, even as members of his enemy party: people.Nix himself narrates the story of his experience with a human intruder in the fairies’ forest, describing the impish tactics and spiteful threats he uses while attempting to drive the “tallish and oldish and baldish” man away. The truth is, though, that Nix lacks in the wicked magic he professes to have, and he fears the fairy queen who has left him in charge of the forest. The sordid tricks Nix uses to deceive the cottage-dweller into believing he does possess charms never sit well with him, and we begin to see that Nix is not exactly like Puck. He dreams of glory and feigns an overblown pride, but he has an empathic heart of gold and a deep-seated fear that we cannot help but want to quell. Eventually, we learn that not only is Nix not foul, but that he may not be a fairy at all.

by Saddleback Educational Publishing StaffThese traditional reads are brimming with spirited characters and positive values but with a little extra excitement and bite, so hold on to your hats!
