Brothers unite. [graphic novel]

Brothers Hudson, thirteen, and Tucker, eleven, are just two average suburban kids until their mother buys them a scarf and an umbrella at a yard sale. Quickly, the boys realize that these ordinary-looking objects are full of magic, and that, with the help of their squirrel sidekick, they can use that magic to fight evil. They move from fighting their neighborhood nemesis to facing bigger foes, renaming themselves Stretch and Brella, the unstoppable brother superhero duo. Soon, they find themselves in another realm, where they take on enormous dragons and an evil knight in an incredible adventure.
