Chirrut Imwe and Baze Malbus were audience favorites the instant they made their first appearance in Rogue One. Unfortunately, viewers’ time with both characters (played by Donnie Yen and Jiang Wen respectively) was short-lived… until now.

Thanks to Greg Rucka’s new middle-grade adventure, aptly titled Guardian of the Whills, eager readers can follow Baze and Chirrut’s adventures before the events of the Star Wars stand alone film. And as you can read in the excerpt below, the blind former guardian of the Kyber Temple and his friend (who has since shrugged off their former role) are working to resist the Empire’s forces that have taken over Jedha, and protect the residents of the Holy City.

However, their plans change with the arrival of Saw Gerrera, a rebel looking to take down the Empire. But while this gives both men a chance to actually help the people of their city, the price it requires might be too high to pay.

Guardians of the Whills is currently available for purchase. Order it here.
