Moon Knight v01 - Lunatic (2016)

Collects Moon Knight (2016-2017) #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!
