Time Travel discussion

Has anyone read this book by Ben Elton? I just picked it up but already has me hooked at just four chapters in. One chapter deals with Sir Isaac Newton as he forms a secret organization. The main character, Hugh Stanton, is depicted rather well, believable and real.

I just finished listening to the audiobook version of this book.
I did enjoy it, there was some very nice time travel elements but it did slow down in the middle a bit and I was disappointed in one of the characters, I think they could have went in a different direction. The ending was however very good and I think worth it in the end.
It wasn't as good as I thought it would be but it's definitely worth a read.
