Sour Grapes

From publisher blurb:

Trouble at the Vineyard

A mysterious plague has broken out in the town of Norwith, which defies both explanation and all attempts so far to find a cure. Tasked with tracking the plague to its source and putting an end to it, a band of mighty heroes must follow the evidence to a local winery. But all is not as it seems in the vineyard, whose crops are stalked by undead plant creatures, and whose casks contain necrotic guardians. Can your party put a stop to the artificial plague, or will they find themselves crushed underfoot like over-ripe grapes?

Sour Grapes is a Pathfinder Roleplaying Game adventure for four to six characters of 6th to 8th level, and is designed to be completed in a single 4- to 5-hour game session.
