When I was in elementary school, I discovered Susan Fletcher's Dragon's Milk on one of my comprehensive trawls through the local library's shelves, and I loved it. The personable dragons, strong young main character, and light, uncomplicated romance appealed to me, and I eagerly worked my through the other two books set in that world. When I heard that Ancient, Strange, and Lovely was going to be another book set in that world, I was extremely excited.
Imagine my surprise, then, when I discovered that AS&L is set in the near-future real world. This was extremely jarring. The previous books were clearly a fantastic land with its own geography, history, and so forth, and yet now the main plot device has been transplanted into Eugene, Oregon. Granted, a Eugene that is happening in the future, but still one with recognizable technology, brand name foods, and an internet that works exactly like our internet (so not that far in the future).
Okay, so all of that was weird, but the writing was good, the characters once more enjoyable, and dragons are awesome. Then, partway through the book, we discover that one of the characters has read Susan Fletcher's other dragon novels.
I almost put the book down in disgust then and there. Aside from the sheer hubris of having one of your own characters read your novels, this little detail opens up a huge world of continuity problems. Did Dragon's Milk happen in our world after all (it certainly follows no recognizable geography, ethnicity, or culture that I can think of, if so)? Or if Dragon's Milk was fiction, then how the hell did it get all the details so exactly right? The problems go on.
If Ancient, Strange, and Lovely had been set in a world very similar to ours but with different names, it would have worked. If the characters had never heard of Susan Fletcher's earlier books (in the same series, no less), it would have worked on the strength of the writing and the characters with the setting just a niggling annoyance. But the conflagration of a real-world setting with knowledge of books written in the same series really badly harmed the overall believability of the novel. Nothing after that point in the book really rang true; instead, the curtain having been thrown aside, plot points felt contrived and doubt was thrown on the previous books in the series, as well.
I cannot really recommend Ancient, Strange, and Lovely. It was overall an enjoyable read, the characters strong and interesting, but at the end of the novel the whole thing rang false.
