Shadowfever by Karen Marie Morning (Fever #5) (Hardcover)

“Evil is a completely different creature, Mac. Evil is bad that believes it’s good.”

MacKayla Lane was but a child when she and her sister, Alina, were relinquished for adoption, forever expelled from Ireland.

Two decades later, Alina lies dead, and Mac returns to the country that cast them out, driven by a relentless pursuit of her sister’s murderer. However, her quest takes an unforeseen turn when she uncovers her lineage, a heritage both endowed and cursed, entwining her in a clandestine chronicle—a timeless conflict between mortals and immortals who have dwelled among us, concealed for millennia.

What ensues is an alarming sequence of events marked by devastating repercussions. Mac grapples with her grief while resolutely continuing her mission: the acquisition and mastery of the Sinsar Dubh—a tome of forbidden, shadowy sorcery authored by the mythical Unseelie King, holding within it the power to forge and obliterate entire worlds.

In a monumental clash between humankind and the Fae, the pursuer transforms into the prey when the sinister influence of the Sinsar Dubh turns upon Mac, leaving a deadly trail of destruction among those she cherishes.

Who can she lean on? Who can she have faith in? Who is the enigmatic figure haunting her dreams? More importantly, who is Mac at her core, and what significance lies in the destiny she glimpses within the ancient tarot card’s obsidian and crimson motifs?

From the opulent luxury of the Lord Master’s penthouse to the grimy depths of an Unseelie nightclub, from the passionate embrace of her lover to the dread-infused encounter with the Unseelie King, Mac’s journey compels her to confront the integrity of her exile and make a weighty decision that could either preserve the world or usher in its ruin.
