I know Dean Koontz is a famous novelist, and apparently (according to the flyleaf) there have been several other Trixie books before this one, but I’m afraid I wasn’t as impressed as I wanted to be.  The theme is one that kids can relate to: how long a week seems when your best friend is gone.  The pictures are cute.  The ungrammatical parts are probably done on purpose for some reason, but they didn’t really seem to add to my experience of the characters or the story, and I tend to think if you’re putting improper grammar in front of kids there ought to be a good reason for it.  There probably was, but I couldn’t discern it.  It’s trying to read like a poem, but I didn’t find the flow to read all that smoothly.  Over all, it was fine, but not I wasn’t wowed by it.
