Mask of Shadows is the first in a series that is great for any fantasy lovers. Living in a post-magical world, the characters in this book must make due with arrows, daggers, and shields to do their dirty work. While it hit all my personal sweet-spots for the traditional assassin competition plot line, this novel’s main character, Sal, was the most intriguing part. Sal is a gender fluid thief who enters the competition for a chance at revenge. Having a gender fluid character in a fantasy setting is a very welcome change to the traditional narrative and allows for greater diversity within the rest of the book. Highly recommended for those looking for more LGBT representation within the sci-fi/fantasy genre and in YA at large.
