Here’s the cover for our next graphic novel! Commissioned by Harper Collins, it will be published under their Big Cat imprint @bigcatbookslikeme on June 5th 2023 under the names John Chalmers and Sandra Marrs (instead of Metaphrog). Included in this post are also the different covers we proposed. When Freya stands to be clan chief, she is falsely accused of witchcraft. She must flee for her life, running frantically through the Scottish countryside, a search party on her trail. Freya must draw on all her bravery and resourcefulness to survive. #graphicnovels #kidscomics #scotland #scottishauthor
