WordlyVision: I didn't like that series much. IMO, it was more marketing/hype than anything. And they just keep recycling the plots from book to book. It is a miracle that no one seems to get tired of the same old same old. By recycling, I don't even mean recycling creatively. All they do is have what had happened to some cats to happen again to their children. The characterization is quite poor -- every cat acts like every other cat. You can't tell them apart. No distinct, memorable personalities. The description passages managed to sound like purple prose without even using big words.
At first, at least the suspense pulled me in. But as the plots got increasingly recycled, even that no longer did the job. I think the only reason it sells is because of the marketing strategy. Every book sounds like a giant infomercial, "want to know the secret? Buy this book!" Okay, there is nothing wrong about a story that instantly pulls the reader in, but the problem is, it is all the stuff OUTSIDE the covers, not within, that pulls the reader in. The franchising, spin-offs, as well as "sneak previews" and other gimmicks all play a role. Quite frankly, everything BUT the story itself does the selling.
