In 1925, earthquakes and a rising sea level left Lower Manhattan submerged under more than thirty feet of water, so that its residents began to call it the Drowning City. In Joe Golem and the Copper Girl, hard-nosed private detective Joe Golem and his employer are faced with one of their strangest cases yet. When a young mother named Rachael Blum arrives on their doorstep, frantic about the bizarre changes in her daughter's appearance and the terrible dreams plaguing the girl, it's up to Joe to separate nightmare from reality. But Joe Golem knows better than anyone that sometimes, the two are one and the same.
