As a thank you, here's a link to a brand new short story set in the Firecaller world, called Salt Mage.
Set four years before the events in Fire Mage...
Nate's only been a bonded Salt Mage for a few months, but he's already regretting the rash decision to give away five years of his life to the volcano salt mines...
The promise of wealth no longer seems so impressive - especially since he's discovered most mages die before reaching the full term.
When he's offered the chance of a way out of his contract, he takes it.
Only problem is, the alternative turns out to be far more dangerous than what he was sent into the volcano to do...
