Yen Press has announced two new Star Wars manga for release this Fall, both tied to licenses of Star Wars content other than the films and set in the era before A New Hope.
Star Wars Leia, Princess of Alderaan, is based on the YA novel, Leia: Princess of Alderaan, by Claudia Gray. This is the second manga adaptation of work by Gray published by Yen Press; it previously released Star Wars: Lost Stars in 2017 (see "Yen Press To Publish ‘Star Wars’ Manga"). This is the story of how a young Princess Leia discovers that her parents are leaders of the nascent Rebellion and is faced with a choice.
VIZ Media has also published Star Wars manga; earlier this year it released Legends of Luke Skywalker, The Manga (see "VIZ to Publish ‘Star Wars’ Manga”).
