The Ice Queen (The Dark Queens, Book 3)

vil has come to Luminesa's forest. The Goblin has stolen three innocents and thrust them into a violent and terrible time loop - in her own lands. And the only way to save them is to go to them herself. But there's a problem, because the moment Luminesa steps foot inside that magicked place she too will get sucked into the Goblin's nefarious scheme. Freedom can only be had if she can figure out the riddle of the key, and she only has one month to try. Failure means death for them all.
