The Blood of Crows by Alex C. Pierce

SPFBO8

Ren, a state-trained thief working in a world where everyone has magical ability except for him, doesn’t kill people. Tensions are already high in the walled realm of Lenmar, and when the nobility start dying with no trace of magic that isn’t from the victims, Ren immediately becomes the prime, and only suspect. Hunted by magic-eating Inquisitors and the Captain of the Royal Guard, his life becomes one of flight and fear through a realm on the brink of civil war.

All Ren wants to do is stop a serial killer, clear his name, find his mentor, and protect the people he cares about. To do that, he’ll have to pull one more high-stakes heist— And steal the proof he needs from the very people who want to catch him.

The Blood of Queens by Alex C. Pierce

What happens when you take a thief and a con-man, that everyone thinks is a monster that should be locked away, and make him captain of the Queen's personal bodyguard? Gossip, treachery, and paperwork... So much paperwork. Ren's appointment as Warden, the Queen's personal bodyguard and head of her security has created something of a stir in the walled realm of Lenmar. Opposition to his mere presence within the Crystal Palace is high, and old schemes and rivalries are kindled anew as the tension builds between the nobility and the factions pushing for change. Ren just wants to keep the Queen safe, solve the mystery of his mentor's disappearance, and figure out why, Haim, who'd saved his life and been his accomplice on more than one occassion, was avoiding him. An attack on the eve of the Moon Festival, when the Council of Nobles is set to convene, provides the spark to ignite a chain of events that threatens the very foundations that have kept the people of Lenmar safe, and puts everyone Ren cares about in danger.
