...that I wonder if it...

I've noticed that I sometimes say things like:

"Here's a book that I wonder if it's good."

It seems ungrammatical to me, but I can't think of a better to express something like this. "Here's a book. I wonder if it's good." just doesn't convey the same meaning to me... Do other people use this sort of expression?
