The Wisdom's Grave Trilogy

Marie Reinhart is an NYPD detective on the trail of a serial killer. When she sleeps, though, she dreams of other lives; she dreams of being a knight, in strange wars and strange worlds. On the other side of the city, Nessa Roth is a college professor trapped in a loveless marriage, an unwilling prop in a political dynasty. She's also a fledgling witch, weaving poppets and tiny spells behind closed doors. When Marie's case draws her into Nessa's path, sparks fly. What comes next is more than a furtive whirlwind affair; it's the first pebbles of an avalanche.

When NYPD detective Marie Reinhart met Nessa Roth, a Manhattan socialite and dabbler in the occult, sparks flew. Then came the gunfire. Nessa and Marie are the Witch and her Knight, characters from a fairy tale brought to life and trapped in an endless curse: to meet, fall in love, and be torn from each other’s arms by violent death, again and again for all eternity. Now they have one slim chance to escape their doom. It lies in Wisdom's Grave, the resting-place of the first witch who ever lived, and the wellspring of magic.

Believing her lover has been killed, Nessa - the living archetype of the wicked witch and a fairy tale brought to murderous life - flies across the Mojave Desert on a mission of vengeance. Meanwhile, Marie is stranded on a dystopian, parallel Earth, forced to confront her own dark side as she comes face-to-face with the architect of an insidious plot.
