Book of Micah is also the name of a person, Micah.

Micah, called from his rustic home to be a prophet, leaves his familiar surroundings to deliver a stern message of judgement to the princes and people of Jerusalem. Burdened by the abusive treatment of the poor by the rich and influential, the prophet turns his verbal rebukes upon any who would use their social or political power for personal gain. One-third of Micah's book exposes the sins of his countrymen; another third pictures the punishment God is about to send; and the final third holds out the hope of restoration once that discipline has ended. Through it all, God's righteous demands upon His people are clear: "to do justly, to love mercy, and to walk humbly with your God" (Micah 6:8).

The name Michayahu ("Who Is Like Yahweh?") is shortened to Michaia. In Micah 7:18, Micah hints at his own name with the phrase "Who is a God like You?" The Greek and Latin titles of this book are Michaias and Micha.
