The Darkening (The Divided Realms, 2)

Life is returning to normal since Willow defeated the faerie prince who had ensnared Mistolear in a deadly game. She is refining her skills at Mage School and spending time with her new friends, especially Brand, the handsome knight who has sworn to protect her. Unfortunately, he also drives her mad with his old-fashioned rules about "proper courtship."
The peace does not last, however, as a misstep in Clarion dooms Willow to play another twisted faerie game. If she loses, faeries will once again be free to wreak havoc in the realms of Mistolear and Earth. The Game Master, King Jarlath of the Unseelie Court, throws Willow and Brand into the Goblin's Gauntlet where goblins, phookas and a host of bloodthirsty creatures are on the hunt. In a surprising move, Jarlath sends his own children into the game as well. Dacia, the female twin, is ruthless and cunning. Theon, the male, is clever, flirtatious and, like all faeries, devastatingly beautiful. Willow struggles to resist Theon's charm, while Brand's jealousy simmers—but with the fate of two realms hanging in the balance, both must push their emotions aside. Can Willow and Brand trust the faerie siblings, or is there more than one game being played?
