Collects Moon Knight (2016) #1-5.

Marc Spector — a.k.a. Moon Knight/Jake Lockley/Steven Grant — has been fighting criminals and keeping New York City safe for years…or has he? When Marc wakes up in an insane asylum with no powers and a lifetime's worth of medical records, all of his identities are called into question. He's surrounded by faces: haughty doctor, hostile orderlies, vacant-eyed patients. But maybe those faces are just masks. Some might hide friends, others enemies. Or even worse: gods and monsters! Marc's got to get out. The moon is high, the mask is on — but if he succeeds in escaping, will he find only a city of sand? And what will it mean when Marc Spector comes face-to-face with…Moon Knight?! Everything you know may be wrong — and you'd be insane not to find out for sure!
