Witch's Sacrifice

Some doors can never be closed…
Evelyn Hemlock is gone, but her actions have cast ripples through the supernatural world. Now the gods that once threatened our survival are on the brink of returning, and Evelyn is prepared to do anything to meet their challenge.
Starting with kidnapping my friends.
To save the people I love, it's up to me to dig up my coven's dark secrets in order to bring Evelyn down. Defeating her might mean dooming myself to suffer the Hemlocks' curse in her place, but if I let her live, then the Ancients will devour the world.
One way or another, this is the end of the Hemlock Coven.
Witch's Sacrifice is the final book in the Hemlock Chronicles series.
