In The Company of Wolves II: Follow The Raven (Volume 2)

A Native American bounty hunter tests his paranormal spy team's worth in a hunt for his long-lost sister in the second series installment. Larranaga doesn't waste time setting up the next chapter in Quin Lighthorn's adventurous life. 
Lighthorn is back with the FBI, training with three other people who have sixth senses. The hope is that the team will be able to track and find terrorists by simply using their minds. However, the rigorous training at a Minnesota mental institution is taking a toll on some trainees, leaving them suicidal or getting them locked up. The agent leading the training, Kruse, has worked with Lighthorn in the past and believes that he's stronger than the rest of the team. Kruse decides to give them a real assignment: finding Lighthorn's sister, Autumn, who was kidnapped 12 years ago when their parents were murdered.
