This is another great thriller set in the city of Manchester. On this occasion, a paramedic, Jem, and a policewoman, Rosie, are continually thrown together in cases involving puddles and moisture. Because Manchester is a soaked city.

Jem and Rosie have been very interesting characters. Jem is an asthmatic paramedic who comes from an adoptive family after having been through the foster system until she was eight years old. And Rosie is a police a bit badass with a wicked sense of humor and with some family issues, also.

The plot of this story is about teenagers who are caught by an abusive net. Rosie and Jem go discovering pieces of the plot in each case in which they find themselves together, first by chance, latter not so much. They also discover their attraction, but both are a bit indirect in their approach. It's fun sometimes, this insecurity and indecission, but is also frustrating and even sad.

The story has a good pace, the police plot is well developed and well resolved. My only complaint is that there are too many words that are local jargon. That led me to go to the dictionary more times than usual and I haven't always found them.
But without taking this into account, this book is a very good read, highly recommended.
