Drink Deep (Chicagoland Vampires, Book 5)

Clouds are brewing over Cadogan House, and Merit the vampire can't tell if this is the darkness before the dawn, or the calm before the storm. With the city itself in turmoil over paranormals and the state threatening to pass a paranormal registration act, times have never been more precarious for the vampires. If only they could lay low for a bit...

Then magic rears its ugly head when Lake Michigan turns black. The mayor insists it's nothing to worry about, but Merit knows a panic is coming. She'll have to turn to friends old and new to find out who's behind this, and stop them before it's too late for both the vampires and humans.
