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. (from Goodreads)
The types of amber keep expanding in this series. The more esoteric ones have been kept secret, but that’s the Guild for you. Now that I know she is bringing the Arcane Society into this series, I can see more and more hints of what is to come.
The next books in the series, sort of, are actually Arcane. They lead into the next Harmony book.
