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

Habakkuk ministers during the "death throes" of the nation of Judah. Although repeatedly called to repentance, the nation stubbornly refuses to change her sinful ways. Habakkuk, knowing the hardheartedness of his countrymen, asks God how long this intolerable condition can continue. God replies that the Babylonians will be His chastening rod upon the nation--an announcement that sends the prophet to his knees. He acknowledges that the just in any generation shall live by faith (Habakkuk 2:4), not by site. Habakkuk concludes by praising God's wisdom even though he does not fully understand God's ways.

Habaqquq is an unusual Hebrew name derived from the verb habaq, "embrace." Thus his name probably means "One Who Embraces" or "Clings." At the end of his book this name becomes appropriate because Habakkuk chooses to cling firmly to God regardless of what happens to his nation (Habakkuk 3:16-19). The Greek title in the Septuagint is Ambakouk, and the Latin title in Jerome's Vulgate is Habacuc.
