Something's rotten in the Fey lands. While Marcus Bramble tracks the lunatic who started it all, Elizabeth and the crew at the Embassy sort through the evidence he left behind. With Lockland back, and the revels behind her, Liz's world is slowly returning to normal. But on both sides of the borders, shadow creatures spring out of nowhere, and the dark legends surrounding the fey take on a whole new meaning.Now time is against them. On the mortal side of things, protesters rally to close the borders, politicians descend on the Embassy, and something that shouldn't exist stalks Elizabeth through the city. In his world, Marcus faces a madman with answers he doesn't want to hear. The Fey rulers turn a blind eye on forests teeming with imaginary monsters, and the Sidhe tower stands silent amidst the chaos. Will the race to uncover its secrets solve the mystery of the elves' past or unleash even more horrors on them all?
