In A Holly, Jolly Murder, Arkansas bookseller-sleuth Claire Malloy rings in the holidays with a Druid ritual, a run-in with a witch, and a far from ho-hum case of homicide. When Malthea Hendlerson, the self-proclaimed Arch Druid of the Sacred Grove of Keltria, wanders into the Book Depot looking for New Age titles, Claire Malloy assumes the elderly woman is a harmless eccentric. Then Malthea invites her to attend a winter solstice celebration at the Sacred Grove. Feeling restless, Claire is actually looking forward to a traditional bonfire in a fir grove. What she gets, however, is murder.
