Bryn Kendrick has had a tough few months. He found out that his partner in the arts and antiquities division of the South Wales Police force, Jason Carlisle, is half fae. Bryn's visited the Fae world, met elves and the blue-hued Trow, and seen and participated in magic.

After a really bad day at work, Bryn heads out to get a drink or two and get laid. Bryn hooks up with Trevor Hannah, a local post-graduate student. They hit it off so much so that Bryn gives Trevor his card. The next day, Bryn gets a call from a local hospital. His card is the only ID on a comatose attack victim. It's Trevor.

Bryn finds out that Trevor is another of Jason's fae father's half-human children and the Trow have struck again. The problems of the Fae world reach into the human one a third time. Trevor and Bryn together have some of the answers. In the end, it may take all the half-fae and their significant others to stop the Trow. Can all of Emrys's children come together in time to save him from betrayal and magick gone wrong?
