Monster Planet (Monster Planet #3)

Blair Spencer and her team have formed an uneasy truce with the monsters led by the vampire lord Xavier Drake, and just when it looks like they may escape Chicago and complete their mission to find a cure for the virus, they find a new enemy standing in their way. Spencer is starting to realize that neither the reptilian creatures they face or the monsters of legend they fear are the real threat... and that the thing she should fear the most is her own species.
