As I reviewed Chronicles, it's only fair that I review Numbers.
As EUK says, Numbers is effectively an additional chapter of Chronicles, and I have to say it rounds the story out nicely. The ending of Chronicles gives the impression that everything is going to end well, but you don't actually know that.
If you've read Chronicles, then Numbers is a must, if you haven't read it, I suggest you read it first, it's well worth it.
