In Masks, Avari and Chayton met, became rivals, friends, and boyfriends. In Raven, Avari found out more about his past, and (begrudgingly) made a new friend. In Falcon, both Avari and Chayton have to deal with the consequences of their actions, and decide how to move forward, and if they will move forward together.
Amara Lynn's Masks series starts off as a villain/hero m/m romance from the point of view of the villain. Over time, Avari becomes an antihero of sorts, makes friends, and opens his heart to love for the first time in both romance and friendship.
The Masks Legacy edition contains the first three Masks books all together, plus six short stories, three of which were previously only available on Amara's Patreon.
