Elliot and the Yeti Threat — Jennifer A. Nielsen

WARNING:

If you care at all for planet Earth, you will pay very close attention to the lessons inside these pages. We usually ask you to run away from dreadful things. But now, you are warned to turn the pages as fast as you can read them. You must know what happens inside this book to learn whether Earth gets destroyed. Because let's face it -- that would be a bad thing.

As King of the Brownies, Elliot has battled Goblins, tricked Pixies, and trapped a Demon. But now, that Demon has escaped and he's ready for revenge. Elliot will face a challenge unlike any he's seen before.

The Last Underworld War is about to begin...
