Query: Kind of flat

I dont see why this book has such high reviews. I like Sleator normally, but this book lacking something that the other books Ive read by him dont; Marco's Millions, the Last Universe etc. A broader plot for one. And characters that I kind of care about. I find it hard to have empathy for these incest minded charaters. The only thing I got from the book is a strong desire to want to read minds!!!!
