Lucien Moreau is a vampire with ambition as sharp as his fangs. Rising through the ranks, he works in the shadows, scheming behind Prince Demetrius Nephus' back to reshape the world. He dreams of vampires standing openly at the top of the food chain, ruling without fear—but the prince knows such recklessness will bring disaster. Yet Lucien finds an unexpected ally in Father Peter Murphy, a priest with his own secrets. With Peter’s help, Lucien climbs higher than anyone dared imagine, reaching the Vatican itself. And soon, power is within his grasp. 

This vampire series isn't for the faint of heart!

The Dreaming Lands is more of an umbrella term for a large project that spans across multiple dimensions. You won't need to read these  books to get the full story, but they have their own interesting storylines that all tie in to the main plot. These novels happen at the same time as The Dragons of Shadowhold.
