I first encountered Mary Stewart's novels on my mother's bookshelf when I was thirteen. Mary Stewart's Merlin novel The Crystal Cave is my favorite (and by "favorite" I mean one of my top five favorite novels), but her romantic suspense novels aren't far behind. I reread them every few years.
The Wind off the Small Isles is a 1968 novella that was "long-lost," which I assume means that someone eventually got around to tracking down Mary Stewart's published short fiction. The novella is romantic suspense, but - unlike most of her novels - it isn't crime fiction, which helps to shorten the storyline.
What suffers most from the shorter length, I think, is the romance. Even though Mary Stewart drops an appropriate foreshadow of love at first sight, it's rather difficult to see what draws the hero and heroine together, other than good looks and an ability to survive the travails of a volcanic island. Character development suffers especially. All that I gathered about the hero is that - like all Mary Stewart heroes - he is charming, handsome, intelligent, affectionate, and alarmingly competent in crises. All that I gathered about the heroine is that - like all Mary Stewart heroines - she is charming, beautiful, intelligent, affectionate, and alarmingly competent in crises. Clearly, the two are well-matched for each other, but there never seems to be any doubt about that. In a word, there is no conflict, which makes for a rather dull love story. The suspense is exciting, however, which helps to make up for it.
Where the novella shines is where Mary Stewart's stories always shine: in the combination of landscape and history. I always want to grab a map and encyclopedia after reading her novels, because she makes the setting as exciting as the characters. In this case, the setting is one of the Canary Islands, and the fun is in trying to predict exactly what aspect of the island is going to end up getting the heroine into trouble. In the meantime, the description of the island is lush, the minor characters are interesting in their own right, and the history is vibrant. This story made for a delightful lunchtime reading.
