My greatest enemy has always been myself. Over the past few weeks, I've painstakingly put my broken pieces back together, from the dark mysteries of my past to the heartrending conflict of my present.

But just when I finally start to feel whole again, everything around me falls apart.

Lallakai, the newly ascended Queen of Shadow and Death, betrays us and takes Zak prisoner. Echo, the powerful fae I thought would help save Zak, threatens to kill me. And Ríkr's nemesis, the ruthless Summer Queen, is hunting him again.

With the four ancient fae poised to battle for supremacy, I'm the only one who can prevent a catastrophic clash of their power. But stopping them will require more than druidic magic. It'll take an act of destruction as devastating as they are.

I'm about to test the strength of my scarred heart, and if I fail, I'll end up destroying everything—and everyone—I'm most desperate to protect.
