Seaton, Cat

Seven years have passed since the disastrous events of BOOK 1, and now it's time for Sibylla to face her curse-breaking destiny. When Troll Kingdom soldiers arrive in the once-safe town of Fiskeby, she's forced to flee up the Glass Mountain. But the moment she steps foot on Troll lands, she's thrown into a jail cell, where she discovers her amnesiac ex-fianc? is set to wed the Troll Queen's daughter. Using all of her wits, she must convince the princess to turn against her own mother, or else face execution on the day of the wedding-and doom the kingdom to remain cursed forever.

"Sibylla always wanted adventure, but she didn't know it would come in the form of a giant, magical bull. Is he a man or a monster? And who knew a prophecy could be so literal?"--OCLC.
