Ahh...Follett.
I liked Code to Zero and The Third Twin. He uses plenty of expletives though ...
This is the first one of his I've read, and of course it's totally unlike the rest of his stuff, being mediaeval and all that. It's OK so far, but a bit erm, unchallenging. Don't know if I'll finish it.
You shoud try reading The Third Twin. Plenty of twists and turns in the plot. As good as Ludlum at his best.
That's a compliment, is it? Not my sort of thing, really.
