Introducing Ripley Plimpt, an eleven-year-old boy whose ordinary life is turned upside-down when he discovers that monsters are not only real, but are also in desperate need of his help to overcome their very real problems. One foggy night, while searching for monsters in the cemetery behind his house, Ripley finds and rescues the tiniest of bats impaled on a thorn bush. What Ripley doesn't realize is that he's just saved the life, or "un-life", of one of the world's most dangerous night creatures--a vampire! Word spreads among all monsters of Rip's heroic gallantry and kindness. Before long, legendary and mythical monsters from around the world are showing up on his doorstep proclaiming Rip as RIP, M.D.--Monster Doctor.
