Publisher's summary
''Baze and Chirrut used to be Guardians of the Whills, who looked after the Kyber Temple on Jedha and all those who worshipped there. Then the Empire came and took over the planet. The temple was destroyed and the people scattered. Now Baze and Chirrut do what they can to resist the Empire and protect the people of Jedha, but it never seems to be enough. When a man named Saw Gerrera arrives with grand plans to take down the Empire, it seems like the perfect way for Baze and Chirrut to make a real difference and help the people of Jedha. But will it come at too great a cost?''
