The Tales of Tanglewood fantasy series melds together influences of Celtic and Irish mythology with modern-day folklore. In the second tale, "The Curse of Satyr Stump", Colin, Blood of the Fey, returns to Tanglewood shortly before Sahwen night, a time when the magic of the 'wood has a strange effect on all things within it.

Things have entered the 'wood that should not be there, and the pathways are no longer safe. The blackberries have spoiled, a pooka roams the 'wood, and a strong calling pulls Colin close to Satyr Stump, where Fionn the satyr has been cursed by Grainne, the Grey Lady.

Tasked to face the dark druidess and help break the curse upon Fionn, Colin seeks help from the druid Bairtlemead Muffingrow, the ferrish Ailfrid, and the elfin girl Deidre. But it will be the satyr chieftain himself who joins Colin, seeking to help restore another piece of Tanglewood that has been claimed by deiney corruption.

But the Grey Lady will not yield so easily, and Colin and Fionn are both nearly powerless in her domain. Colin learns very quickly that during Sahwen, Tanglewood can be a very dangerous place indeed.
