Of Spells and Curses. Wardens of Estralia, #3

Darkness stirs in the ruins of two worlds. When Randal disappears without a trace, Vivienne and her fellow wardens must cross forbidden realms to find him. Their search uncovers a rising power older than the void itself, one that twists magic into living curses. As old secrets come to light, Vivienne's bond with Diego deepens, but so do the dangers around them. The veil between worlds weakens, and forces once sealed away begin to wake.
To save their mentor, the wardens must face what even the Archdruid fears to name. The past is calling, and this time, it wants blood.
