Well, I don't have any idea what happened to the post I wrote reviewing Test Pattern. It's gone from the edit queue so I'll be darned if I know what happened. I could try to recreate it but I'm just not feeling it right now. So here's the executive summary version:
It's a decent book. Probably worth picking up if the theme--the effect of television on a 1950s working class family--seems like it might be interesting. It certainly has its own unique charms, and, though I wasn't really drawn in by the gimmick (the idea that there's more in the test pattern than just a test pattern, at least for one little girl), I was drawn in by the unique narration style and the effective characterizations. It was Marjorie Klein's first novel and I think it's always a good idea to support first novels. So there you have it.
I'm also not sure why The Jump doesn't seem to be working any more. It must be the computer's fault, as I am wholly innocent.
