Right after Disney disavowed the expanded universe, they made it known that they're keen on expanding the hell out of Star Wars once again. In addition to explaining how Captain Phasma escaped certain death in Force Awakens by way of a comic, they're also commissioning a book that serves as a prequel to Star Wars Battlefront II, which is also said to be cannon.
Christie Golden will be penning Inferno Squad, a novel that's set between episodes IV and V, that takes a look at the history of the elite special forces team that witnesses the death of the Emperor and the destruction of the second Death Star on Endor. It's out on July 25, well before the release of the game on November 17.
Sidling up a previously unheard of yet formidable team within the narrative of the original trilogy is a smart, and safe move -- it'll probably pay off.
