Masters and Mages, book 1: Cold Iron
Miles Cameron2018

Aranthur is a student. He showed a little magical talent, is studying at the local academy, and is nothing particularly special. Others are smarter. Others are more talented. Others are quicker to pick up techniques. But none of them are with him when he breaks his journey home for the holidays in an inn. None of them step in to help when a young woman is thrown off a passing stage coach into the deep snow at the side of the road. And none of them are drawn into a fight to protect her.
One of the others might have realised she was manipulating him all along . . .
A powerful story about beginnings, coming of age, and the way choosing to take one step towards violence can lead to a slippery and dangerous slope, this is an accomplished fantasy series driven by strong characters and fast-paced action.
