Send Me Their Souls by Sara Wolf

There are worse things than death.

With the rise of Varia d’Malvane comes the fall of the Mist Continent. Cavanos is overrun by the brutal rampage of the valkerax, led by its former crown princess. Vetris is gone. Helkyris is gone. As each mighty nation falls, the grip of the crown princess closes around the throat of the world.

But Zera Y’shennria isn’t out yet.

Alongside Malachite, Fione, Yorl, and her love Lucien, Zera seeks aid from the High Witches and the Black Archives, with the valkerax horde hot on their heels. Seemingly unstoppable, Varia can track Zera through her dreams, ensuring there is nowhere to run. Thankfully, an ancient book holds the key to stopping the incursion forever.

But at what cost comes freedom?

At what cost comes love?

At what cost comes the end of the world, and the beginning of a new one?
