From publisher blurb:

Every year, the turnip harvest in the tranquil Bornlandish village of New Wulzen is reason for joy and celebration. This year, the village community celebrates a particularly bountiful harvest, and all are welcome at the festivity, but it quickly becomes clear that this harvest is anything but normal—some turnips even bleed when sliced. Superstitious minds immediately leap to curses, but the evidence continues to mount. A plague of rats overruns the village, farmers suffer evil dreams, and the ghost of a Blessed One of Peraine utters a sinister prophecy. The heroes uncover dark truths from the past as they struggle to investigate these eerie events.

What is the secret of the turnip harvest?
