After reading the reviews posted here I realize that I have missed out on quite a lot of excellent reading material over the years. The only three de Lint books I have ever come into contact with are The Onion Girl, Tapping the Dream Tree, and Spirits in the Wires. Some die-hard fans will therefore, I am sure, immediately discount my disagreement with the seemingly negative opinion of this book shown by the majority of the reviewers here. In particular, I strongly disagree with the review that states, "This one is for the fans... only" because this is the first De Lint book I ever read.
I will freely admit that I am a sucker for a good short story. I must also say that, if the first de Lint I had read was a continuous novel, I might not have gone around town recommending it to everyone I knew, as I did with Tapping the Dream Tree. This might not be as deep or as emotional or as detailed as some of de Lint's other work, but, from my reading of the stories, de Lint writes into these stories as much detail and emotional description as a short story can possibly contain.
As a short-story writer, one of the most difficult things to do well is to leave out parts that you could write in. If you choose well, these left out pieces add to your characters and stories more effectively than their inclusion. de Lint is excellent in this respect. Some of these characters are so well written that you want to step into their world and find out what they are like on a normal day and if they've ever had a normal day and what they like in their coffee or if they like coffee at all. They are characters that have deep wells of untouchably fascinating personality.
In summary... I loved this book. I loved these characters. This is the first De Lint book I ever read. This is still my favorite De Lint book. If you have never read de Lint, and if you like short stories from Bradbury (all of his shorts, not just his Martian Chronicles), and you would like to find a book of fantasy that captures the same feelings of making all things strange and, in strangeness, strangely beautiful, read de Lint's Tapping the Dream Tree. It is good enough to be worth reading.
