Ezra is one of those books that doesn't get much attention, but it takes place on the cusp of the third covenant between God and His people (Adam in Eden, the Hebrews going to the Promised Land, and now the return after the Babylonian captivity that will set up the coming of Jesus). They had been sent to the heart of idolatry and evil, and that world was not that different from our world today. Ezra helps us to see that God expects that we too can rebound from these low points and be great again!
