From publisher blurb:
Trade along the system of rivers and canals known as Gerabe's Run has become embroiled in politics and espionage. In the great, dreaming city of Suzh-Batan, the corrupt harbormaster Ubam Hiddor has raised docking fees and customs taxes. The riverboat captains have banded together, building their own port shortly upriver called Dohn Amuran, from where their cargoes can be moved by land.
This volatile situation is coming to a head. Ubam Hiddor cannot let this challenge to his authority (and wealth) stand unopposed. The boat captains will respond to fire and violence with fire and violence of their own.
The adventurers are the only ones who might forge a peaceful end to this conflict, or at least choose which side will prevail.
Who will die? Who will win? Play to find out.
