Context:

Chris Stringer recommends this as part of a series of novels by Björn Kurtén (identified as a paleontologist from Scandinavia) about the Neanderthal-modern human interface. In the book, modern humans call Neanderthals 'trolls,' connecting to the discussion about whether Neanderthals survive in folklore and legend. Stringer describes the novels as 'really good' and recommends them, noting their exploration of the interaction between the two human species.
