There are three laws when dealing with the fae: never trust a fae, never make a bargain with a fae, and never go near a fae without a protective charm.
The fourth law was unspoken... never fall in love with a fae. Jaye MacCullagh comes from a long line of humans who have taken on the role to guard the mortal world from the devastatingly magical and deceitful Otherworlds, the home of the fae of Irish myths. She always thought she was prepared to survive the fae's cunning unscathed but when her brother becomes ensnared by an Unseelie, Jaye will do whatever it takes to save her brother. Including striking a bargain with a solitary fae named Ravven Crowe. He will make her an assassin capable of killing faeries, but only if they both manage to survive the deadly challenges the courts put forward to test Jaye. Now inexplicably entwined with this arrogant fae, Jaye struggles with whether or not she can trust Ravven. If she doesn't then they will likely both die, but if she does... she might just lose her humanity. Something which once lost, can never be reclaimed. A quest for a faerie killing sword, an unbreakable bond, and one mortal girl caught in the midst. Laws will be broken in this fae fantasy trilogy. With heart-wrenching romance, bitter betrayals, and cunning intrigue this series is perfect for fans of The Cruel Prince, An Enchantment of Ravens, and A Court of Thorns and Roses.
