I agree with previous reviewers that when you start out on this novel part of you is thinking "is this just a re-hash of The Name of the Rose" - no it isn't, it has many echoes, or should that be Eco's, of that great novel but is an of itself as absorbing, if not quite as high in writing style or rich in semiology.
As a frequent buyer from Amazon I always find it frustrating that coming to a series of novels it isn't always that clear in which order one should read them, yes you can sometimes tell by publication date - but these can often be just as confusing...so here for the new C J SANSOM fans is a list in order of their series to 2012, should you wish to rattle off the series before the next publication...
Dissolution (2003), ISBN 1-4050-0542-4
Dark Fire (2004), ISBN 1-4050-0544-0
Sovereign (2006), ISBN 1-4050-5048-9
Revelation (2008) ISBN 1-4050-9272-2
Heartstone (2010) ISBN 0307356183
Hope that helps some of you...and it maybe something Amazon could consider doing on the author page?
