Jaypaw was born blind and since the prophecy is There will be three, kin of your kin, who hold the power of the stars in their paws, I think StarClan felt bad that Jaypaw couldn't live up to his dream of being a warrior, so they enhanced his other senses to make up for him not being able to see.

Anica This book was probably the most exciting book I have read yet in this Power of Three series. It had a lot of drama,action, and more interesting things. I rated this book 5 stars. This book was made by Erin Hunter a group of authors who work together to make an awesome book. It's nonfiction book because it isn't real but that cats in the wild is possible. I recommend people who love these kinds of books read this!
