"I would disassemble this body and cast it onto the coronal burn of the sun if it means I get answers." Thus proclaims the determined Elisabeth Reese, journalist, professor, and joke-cracking nun working in alternate history San Francisco. She has one goal: to rebuild a failed time machine that caused a lethal explosion during its initial demonstration.

With her reluctant protege, a young budding scientist, she searches for the machine's plans left behind by its exiled inventor. But her pursuit is disrupted, threatened by area conflict. A faction of the deadly Al Sayf al Ahmar–the Red Sword–has been rising to power. Lead by the hulking Crazed Herald, Maalik du Mahdi, the Red Sword heed a prophecy that will culminate in a battle between two "one-armed wild men." Du Mahdi is believed to be the first of the pair, while his counterpart could be anyone…even a small, peculiar nun from across the bay.

All Elisabeth wants is to witness the impossibility of time travel, but first she must battle the odds and fulfill the present. Part steampunk and part mystery, Pale Blue Scratch explores the conflict between the senses and logic, and the lengths one may go to resolve it.
