The Dryad Storm by Laurie Forest — book slip

Magical forces clash and Erthia hovers on the brink of ruin in the can't-miss finale of Laurie Forest’s epic fantasy series, The Black Witch Chronicles! Black Witch of prophecy Elloren Gardner Grey has unleashed her powers and embraced her legacy as a Dryad and guardian of the Forest. But the losses—of life, of love—have been almost too great to withstand as the Shadow continues to devour the world. With only a tattered shred of hope remaining, the Bearers of the Wand of Myth must battle their way back to each other to mount a final stand.
