MacKayla Lane's existence is plunged into chaos as the walls between humans and the immortal Unseelie collapse, ushering her into a labyrinth of Dublin's dark streets, treacherous political arenas, and the perilous realm of the Fae. Amnesiac and ensnared by the seductive web of two enigmatic men, Mac must reclaim her memories and muster the strength to confront the Fae Lord Master, the architect of her sister's demise and the catalyst to her own transformation. In a world where allies camouflage their deceit with lies and the Fae's illusions defy reality, Mac's quest transcends mere vengeance—she is the key to humanity's survival against the onslaught of an insatiable immortal darkness.
