The last teenagers on Earth. Brailler M.

Since the monster-apocalypse began in the city, the thirteen-year-old teenager Jack Sullivan has been living in a fortified house on a tree. But he alone cannot cope with the hordes of zombies, winged abominations, bulldozers, and especially with an unusually smart monster known as Grrygh. Therefore, Jack gathers the team: his best-Umnik Quint, a former school bully Dirk, a faithful pet Monster Jack-a tramp-and beloved Jack, June. With their help, Jack is going to defeat Grrygha, to accomplish the greatest feat after the end of the world and become a real hero. Will he deal with this task?
