Way of Shadows
Night Angel #1
A young boy becomes the apprentice to the cities top wetboy [super duper assassins] and grows up. Lots of intrigue and politics and the city falls to a northern kingdom.
Turns out the Wetboy had a magical item and it ends up bonding with the apprentice, allowing him to become the next Night Angel, a creature that is a balance to 6 other magical creations.
It was a bit brutal and graphic. I’ll be reading the next 2, but have no desire to own them. Really well written for a first novel though.
