My overwhelming impression reading this book was one of pleasant surprise. Though I've always enjoyed Susan Cooper's output in the past, considering how little is spoken about this one, I hadn't been expecting it to be as good as it is. The plot unfolds at a nice pace, and details from the beginning resurface at the end in an agreeably rounded denouement. I've given three stars because I believe I gave four to Cooper's The Dark is Rising sequence, and The Boggart doesn't quite achieve their level of soaring beauty, but it really is an excellent little story.
The characters, while not particularly deep, are realistic and original. The villain is appropriately slimy and irritating in that patronizing niceness that grownups often overlook, and that every kid despises. The kids' mom is lovingly rendered: both sympathetic and exasperatingly overprotective, as a mom ought to be. Her son's "layabout" genius friend whom she so distrusts is a strikingly ambiguous detail for such a young audience, as is the hinted relationship between the two helpful theatre workers who first teach the heroes to call the 'weird stuff' that has been occuring by its name, 'Boggart.' Both these details, without intruding onto the story, add subtle layers of authenticity to the world.
Some have complained about the use of technology in the story, saying that it "dates" the book and makes it irrelevant; but honestly, computer technology becomes outdated so quickly nowadays that by that argument one would have to avoid it in literature entirely, and it's scarcely the author's fault that nobody uses floppy discs anymore. I can't see that it detracts from the story in any way. I felt rather intrigued by the glimpse into a time when computer games were an exciting new invention being created by gangs of enthusiastic kids, rather than the massive industry of today. Cooper weaves science in with the magic in a surprising way, and in this as well as in the affectionate nod to show business invites comparison to Madeleine L'Engle.
But the real heart of the story is the Boggart himself. With his satisfyingly mischievous pranks, his innocent delight in fun, and his alien mind (racing blithely, Tinkerbell-style, from one emotion to another, the ecstasy of discovery to brain-numbing sorrow to cheerful curiosity, within seconds) Susan Cooper's little scottish puck is a delicious realization of the trickster spirit.
I wasn't a fan of this audio recording. The narrator just doesn't seem to grasp the frolicking, antic tone of this story; he is booming and august when he ought to be atmospheric, and recites the humorous bits as if he were reading a stern lecture--not in a dry, ironic way, but rather as if he slightly disapproved. He is also apparently under the impression that dramatic moments must be read at a shout, LISTEN TO HOW EXCITING THIS IS, as if the audience couldn't figure out for ourselves when something important is going on.
However, this story begs to be read aloud. Its blend of whimsy, lightly poetic descriptions and slapstick humor make it excellent bedtime-story fodder. While not necessarily life-changing, it would make a great addition to a library; if you want a fun adventure and quality storytelling, you really can't go wrong.
