Princess Meryl and Princess Addie are sisters. Addie is shy while Meryl is outgoing and brave. When Meryl catches the Gray Death, Addie must go on a dangerous journey to find the cure for her sister. On this journey, she conquers fears, fights battles, and learns to be brave. This is one of my favorite fantasy stories. I’ve read it many times. The action in this book is thrilling and the bond between the sisters are touching. It’s a great read!
