From the publishers blurb:
Milk and Blood is a low level, introductory adventure for play in Dark Albion: The Rose War and other OSR systems. It is intended for 1st (or possibly 2nd) level characters, and occurs mostly in the village of Bacton in Herefordshire in 15th Century England, but can easily translate into any fanasy setting. The PCs are called upon to investigate the disappearance of a child amidst a rising tide of pranks and odd goings-on that has caused the local priest to beg for help.
Milk & Blood includes investigation and intrigues with various NPCs, and must work to solve the mystery and even confront a Chaos Cult rising the town and surrounding area -- possibly aiding one powerful faction, and alienating another. Either path may provide useful plot hooks for future adventures.
