On the night of the summer solstice, Obadai Bashim encounters Jules Sterling, a young engineering sage. Jules is on the run from a ripper, an assassin of the Theocracy who has already killed his master. Open atrocities by rippers are unusual in County Isleshire, where freedom and acceptance reign over prejudice. However, political instability between the Five Kingdoms and the Divine Theocracy has set the theocrats on a mission to crown religious doctrine over science, and the Sage’s Guild is number one on their eradication list. If Obadai helps, he’ll have a price on his head too, but he can’t abandon Jules. Escaping the ripper’s clutches is not enough. Jules has a mission of his own: to repair a faulty airship inn about to crash into the fortified township of Dunbruth. Luckily, Obadai has a few magickal secrets up his sleeve.
