In "Highland Journey", Mairi Hedderwick retraces the steps of an obscure Victorian artist, John T. Reid, who made a sketching tour around Scotland in 1876. Hedderwick, a witty and immensely readable author of children's books, achieves so much more than simply following in Reid's footsteps; wonderfully realised, her quest becomes obsessional at times as she struggles to understand her mentor and guide with whom she shares a passion to conserve Scotland's wild places and record them faithfully with exquisite illustration and insightful comment.
