This is one of my absolute favorite books. It takes a while to get started, but once it gets going, it's amazing! My copy is falling apart because seven different people have read it. It's one of those books that is so realistic it's difficult to return to reality after reading a few chapters. I read it when I was a child, but didn't understand it until later. My best friend and I created a make-believe world based on Unicorn Highway. We were so positive that one day Infinity would come gallopping through the woods in her back yard and take us both for the ride of a lifetime. There was a shack near my house that to us, looked exactly like Mr. Tucker's house in the book, and we felt like part of our childhood was taken away when the city demolished that shack last winter. Unicorn Highway is a remarkable book! Get your hands on a copy as soon as possible! You don't know what you're missing if you haven't read it!
