Wings of Fire
Four short stories called Winglets have been written: Prisoner (2015), Assassin (2015), Deserter (2016) and Runaway (2016). These tell stories from the view of secondary characters from the main books (Fierceteeth, Deathbringer, Six-Claws, Arctic, Foeslayer, Snowflake). These short stories have been published in print several times, most notably altogether in The Winglets Quartet (2020).
