"Eleven-year-old Megan and her cousin Joey have a summer job working with computer-savvy mice to spread the word about climate change. But when there's trouble at Headquarters, Megan and Joey find themselves on a cross-country journey to save Mouse Nation, and the planet, from a mysterious enemy"--

Prudence Breitrose grew up in the part of England where Winnie the Pooh once roamed, but now she lives in California. Prudence worked as a health education writer until she had a dream that confused computer mice with the real thing. That got her started on her mouse books-first Mousenet and then the sequel, Mousemobile. Visit her and the Big Cheese at www.mousenet.org.
