Azrael. The Undernet, #2

Milt Edwards, survivor of an incident that almost took his life six months previously, is back. He and his girlfriend, Roberta (Robbie) Jones, both suffer from PTSD as a result of their ordeal, and they attend counseling sessions in order to help them work through their mental anguish. Nothing helps, but then a friend of Milt's is killed, ostensibly by the same person who designed the Undernet-Azrael.
Galvanized into action, Milt once again joins forces with the FBI in order to find out who Azrael truly is, and he is paired with a rookie agent, Nasraana Shaksy, an American Muslim who has her own battles to fight. Together, they stumble upon a child trafficking ring, and Milt comes face to face with monsters of the worst kind-those who walk around in everyday society. The mystery of who Azrael is deepens, and Milt desperately searches for the truth.
The only question is, when he discovers who is behind it all, if he will survive it. Disclaimer: This book contains adult material of child sexual abuse investigations and may not be suitable for anyone under the age of 18.
