Books in the Requiem of Stone series

Alex always wished to see the Overlands, a place of sunshine and freedom. However, as a slave in the far corners of the Underlands, it was all but a dream. That is, until he's framed for murder and is forced to flee during a demon attack. Searching for the answers to why he was framed and seeking a chance at the fleeting freedom he's always dreamed about, he journeys to the capital, meeting friend and foe along the way. But the Underlands are both beautiful and dangerous. Having a demon hunter on his tail and a witch whose sole desire is to become the high Seer around him, he's in for quite the journey.
