This book was categorized as middle school, but my 22 year old self loved it just the same. The concept is that there are some people who can shape shift into any animals. Tess is one of these Switchers.
She meets another Switcher, Kevin, who has lived on the streets for several years. They become friends, and Kevin asks her to help him with a very important task. Basically, saving the world. And there we have our story.
Well written, fantastically imagined, and captivating. This book is a sure 5 star.
