Not only is this book historically facinating, its also incredibly well written and entertaining. It captures the spirit of the times through which Stephanie lived and survived. The story tells of a plucky london girl who has her heart bent on becoming a visual signaller. Despite the naysayers, she becomes one of the best on sea or shore. She scratches out an existence in the harshness of the highlands, taking comfort in her friends, her dreams of romance and her own skill with the lamps. Her characaterisation is vivid and at times hilarious, and you can see the scottish scenery unfold in her prose. I couldn't put it down. Interested in the period or not, I would recommend it to anyone.
