Freak the Mighty is an incredible book. It's incredible because it's so fun to read while at the same time wrestles with difficult and deep themes. The young adult genre is flush with books of all kinds, but one thing that young adult books all tend to stay away from is having the protagonist die. Freak the Mighty bucks that trend by having Kevin die. It's reminiscent of Leslie's death in Bridge to Terabithia because there is a moment when a reader is likely to consider the actual point of finishing the book. A great character and person has been taken away from the reader, and we feel that hurt deeply because we have grown to love that character so much.
Kevin is an amazing character and very easy to love. He is perpetually happy as well as perpetually hopeful. He's got a disease that is going to kill him early in life, and Kevin is brilliant enough and well educated enough to know that there isn't anything that can save him. Despite his disease, Kevin is the character that has the attitude of carpe diem throughout the story. He is the guy seeking out life's adventures, and it doesn't matter if those adventures are real or imagined. Kevin is such a creative and imaginative character that he's constantly blurring the line between reality and imagination. He sees quests and damsels in distress everywhere, and he inspires Max to see that there is much more to life than wallowing in the down under. Kevin is filled with hope, and that hope infects readers and Max, and that is why we are so devastated when we lose him.
