Engaging read that is a mix of paranormal, adventure, buddy-action of FBI team, and good romance. I enjoyed the world-built of shamans, adepts, spirit planes, and spirit guides. Took a while to understand everything but I decided to go with the flow and enjoyed the explanation of how things work.
I thought the reveal of the villain and the motive was coming a little bit out of nowhere, though. So, the mystery lover in me wasn't as satisfied.
But in overall, it was a great start of a new series and I'm looking forward to the sequel.
