Query: fantastic read

I saw with dismay some reviews below gave less than 4 stars. Prehaps they did not read the same book I did. Maybe they made a simple mistake. Mr. Stirling's work is among the best ever. The first read or the fourth read provides the same wonderful experience of entering that particular world, leaving this one behind, not noticing where the time goes and waiting impatiently for the next book. Mr. Stirling's work provides the rare experience of the words on the page vanishing into a world in my mind's eye where I see the action in the book, understand the logic behind their actions and it is all so real.So very,very real. Bravo, Mr. Stirling from a most contented and highly grateful fan.
