Far better than the first two of this series, 3rd Degree is my favourite so far. Where the first two books are about single serial killers who the team of women strive to catch, this book responds to a terror threat and mass murders from a terror group within the United States, who have formed an army of soldiers working against the corruption of the system, for the "greater good" of the whole world. It is a very interesting read, exploring policies and procedure within the department of justice, as well as a side romance, and one of the girls lose their own in the battle. Informative, interesting, humorous and light-hearted, 3rd degree is a definite recommendation from me.
