Mezolith is a graphic novel set loosely in the Mesolithic period (with shades of the Palaeolithic) somewhere in northern Europe. Written by Ben Haggarty, a storyteller steeped in legends of many cultures, which all come through in the book, and drawn by Adam Brockbank, an artist who has worked on X-Men and the Harry Potter films, it packs a punch stylistically but does the content match? Guests helping us decide this are Matt Ritchie from the Forestry Commission Scotland, John Swogger, archaeological comic artist and Erin Kavanagh, geomythologist and poet.
