I was expecting something similar with Nightshade, but whereas Greenteeth was sunlight filtering through the leaves, Nightshade was the pounding rain that tears through empty branches. Set in Roman-occupied Britain, Nightshade & Oak follows Mallt y Nos, a goddess of death in Celtic folklore, who is turned mortal by a wayward spell. Hence transforming Annwn from the Otherworld to the land of the dead works and better supports the plot of Nightshade. In Nightshade, O'Neill reverses days and nights so that when the sun sets in the mortal world, it rises in Annwn. Nightshade & Oak reminded me that strength means something different to each person, but it is important to remember that strength also looks like surviving.
