Adventures await Rector "Wreck 'em" Sherman. About to turn eighteen, he's facing ejection from the orphanage that passed for home. He should also choose a trade, but work is scarce in steam-powered Seattle. And Rector has more unconventional plans. He's started dealing in sap, a yellow narcotic produced by rebels and outlaws within the city's toxic walled enclave. What's worse, he's been sampling his wares. Other problems include being haunted by an old friend with a grudge.
