In a kingdom shrouded by unnatural darkness, a hidden power awakens.

Echo Ferrarius has spent her life in the shadows, convinced her uncontrollable magical abilities bring only destruction. Haunted by the damage she's caused those she loves, she's resigned herself to isolation until the night she's saved from attackers by a group of elite warriors—including Prince Romulus Anastas, second son of the king.

As ancient monsters emerge from the western forests and a mysterious blight withers crops across the realm, Rom believes Echo's Gift may be the kingdom's only hope. Together with his loyal companions, he convinces her to journey south in search of training. But as Echo struggles to master abilities that respond to emotion rather than control, she uncovers disturbing connections between her mysterious heritage and the darkness consuming Harmon.

When betrayal strikes from within the royal family itself, Echo and Rom find themselves at the center of a prophecy that could either save the realm or destroy it completely. For the one who brings light back to Harmon may lose their own in the process.

In this sweeping fantasy of forbidden love and dangerous power, Echo must decide: Will she remain the frightened outcast she's always been, or become the Eversor—the destroyer—who could bring salvation or ruin to a kingdom on the brink?
