The Way of Shadows, by Brent Weeks

I had fun getting lost in Brent Weeks's Night Angel trilogy, starting with The Way of Shadows. In the slums of a city where crime lords hold the power, a street urchin named Azoth tracks down the deadliest assassin the world, Durzo Blint, and begs to become his apprentice. Blint reluctantly agrees to train Azoth, but only if he first kills  the sadistic leader of his street gang.

Weeks makes ample use of fantasy tropes. That kid living on the streets? Spoiler, he's the chosen one. His teacher is a worn-out assassin, grown cynical and weary after these many years of being alone; his girlfriend is a young, morally pure woman who acts as an externalized conscience; his mother-figure is a hooker with a heart of gold.

Other fantasy elements will be familiar, such as legendary enchanted objects and mad wizards. I'm generally okay with this as a reader. One of the joys of genre fiction is seeing how different authors handle different genre conventions. But there are some tropes that could stand to go into retirement, notably: Violence against women as the plot device that motivates the main character to achieve his destiny.

I enjoyed the adventure and careful plotting within the books. These are not advisable if you prefer to avoid violence, but if you can tolerate some squicky scenes, these are adventure-filled, plot-driven stories that will satisfy the itch when you want action and magic. I particularly recommend the audiobooks, since Simon Vance is such an enjoyable narrator.
