Obsidian Prey (Harmony Book 6)

Amber tuner and independent prospector Lyra Dore lost her heart—and her discovery of a rare amethyst ruin—to cutthroat businessman Cruz Sweetwater. At least she had her artistically talented dust-bunny to comfort her…
But the ruin’s mysterious power has put everyone involved with the project in danger. And only by trusting their psychic instincts will Cruz and Lyra survive— and surrender to the desire that binds them.
