Under Winter's Control (Thieves of Winter #3)
Kirsten S. Blacketer

During one of the most anticipated events of the season, Lady Katherine Reddington vanished without a trace. Several months later, the jewels she wore that fateful night appear in the possession of the Earl of Norwich.
Monty has one objective: locate Lady Katherine and restore her to the care of her brother, Edmund. After months of searching every corner of England, the sudden appearance of the jewels gives him a new lead. One that requires Monty venture north into Scotland and into the very conflict he has been desperately trying to avoid.
***Author's Note: This is the Third Book in the Thieves of Winter Series. Can be read as a stand-alone, but I recommend reading them in order to catch all the interwoven plot points.***
