The Last Dragon Slayer (Deathsworn Arc Book 1) by Martyn Stanley

Saul Karza, wizard of the Empire, has been given a quest by the Empress herself: To find and slay a mythical ‘noble dragon’ – said to be near invulnerable.

Instead of leading a large band of soldiers, archers and spell-casters; he sets out with two immigrant dock-workers and a homeless dwarf.

What Saul needs is the legendary ‘Last Dragon Slayer’ on his side, because on this deadly quest, it’s not only Saul’s favour with the Empress that’s at stake – but also his life.
