I was going to rate this only 3.5/5 stars because of the characters' unbelievable choices (why can't Thorn just tell Berry the truth and escape together with Starleaf, Mud, and Frog??), but changed my mind when I read the last few chapters. Erin Hunter created this infuriating climax and cliffhanger that was so engrossing that I loved it. I can't wait for the next book! Keep up the good work Erin!
