Probably one of the best book in the series of an already generalized 5-stars series by me. Kate's relationship with Curran was tested with Kate's hidden insecurities and such. The story started a few weeks after the Midnight Games, around the time when Curran stood up Kate and after. A new player came into town and decided to wreck havoc with magical mutated pathogens which would make Fringe's Dr Walter Bishop giddy which turns out to be a Babylonian legend who destroy cities and brought apocalypse on earth through several millennia who also turns out to be related to Kate. 
 Full review to come.
