The Triads: Book Two of the Triads of Tir na n'Og

In Tir na n'Og, the Greater Fey rule over Man and Fey alike, their will enforced by teams of hand-picked human champions called Triads...
Three Triads, each serving a different faction of the quarrelsome Fey, are called to investigate three seemingly unrelated mysteries. But the clues lead down a dark and bitter path as they are drawn into battle against one another—for the foe they unearth is more subtle and fearsome than any mere monster, and the peace of Tir na n'Og is at stake.
