The Blue Man is a mystery, science fiction novel written by American author Kin Platt.

Steve Forrester is a teenager who goes to live for a summer with his aunt and uncle, who run a rural motel.

On his first day running the desk by himself, a strange man checks in, dressed in a scarf, hat, trench coat and gloves, unusual attire for summer.

Later, Steve brings a towel to the stranger's room and sees something that launches him on an unusual and singular adventure: the man's skin is bright blue and he seems to be draining energy from a nearby lamp.

After his uncle is seemingly murdered by the fleeing Blue Man (who appears to possibly be of alien origin), Steve sets out on a cross-country search for justice and revenge.
