The Grasp of the Crooked Coven series is by far & away, my favorite witch-themed adventure series in 5e. Zeke really knows how to spin an evocative narrative in these modules (I've DM'ed the supplement and Timber Falls books in this series so far). I just bought GCC-2, and with a cursory glance, it looks just as thrillingly awesome as the 2 prior books.

If you like witch-themed adventures, this series is a solid 5 stars for everything so far. Narrative, art, layout and well-received combat encounters. Top Notch!
