The Scholar the Seer and the Renegade Hex

Ancient magic, new world... Charlotte Roseingrave is working hard to build herself the life she has always wanted in 1887 Denver, one that doesn't involve seances, ghosts, or murderous fae. But when a ranch boss dies under suspicious circumstances, she is once more pulled back into the world of the supernatural. Thomas Leighton couldn't be more delighted. Not with the man's death, of course, but with the mystery surrounding it.
When he's asked to investigate, he jumps at the chance. Soon, Charlotte and Thomas find themselves deep in the heart of cattle country, in pursuit of some force that seems to be targeting wealthy investors. It's no mere creature they're up against this time, but something far more dangerous. An ancient power from the dawn of civilization has been roused, unlike anything either of them has ever seen.
As the mystery deepens and the danger grows, Charlotte and Thomas find themselves in a desperate race to find the murderer and counter the magic that's been unleashed, before the entire region is lost to darkness.
