Here is a list of The Traitor Son Cycle Books in Order.
The Red Knight (2012)
From the blurb:
Twenty eight florins a month is a huge price to pay, for a man to stand between you and the Wild.
Twenty eight florins a month is nowhere near enough when a wyvern’s jaws snap shut on your helmet in the hot stink of battle, and the beast starts to rip the head from your shoulders. But if standing and fighting is hard, leading a company of men — or worse, a company of mercenaries — against the smart, deadly creatures of the Wild is even harder.

The Fell Sword (2013)
From the blurb:
Loyalty costs money. Betrayal, on the other hand, is free.

The Fall of Dragons (2017)
From the blurb:
In the climax of the Traitor Son Cycle, the allied armies of the Wild and the Kingdoms of men and women must face Ash for control of the gates to the hermetical universe, and for control of their own destinies. But exhaustion, treachery and time may all prove deadlier enemies.
In Alba, Queen Desiderata struggles to rebuild her kingdom wrecked by a year of civil war, even as the Autumn battles are fought in the west. In the Terra Antica, The Red Knight attempts to force his unwilling allies to finish the Necromancer instead of each other….
