Having read a few reviews about this book it is clear that people either love it or hate it. I have to say that I sit between the lovers and the haters with this book.
Having just finished Engima and been hugely disappointed I was a bit pensive about picking up this book. However, once I got going I found that I was enjoying it. The characters have a lot more depth to them than in Enigma and the pace, though mostly set around Martha's Vinyard in America, is quite quick.
So, I enjoyed the book, but I only give it three stars because of the plot. Whilst Fatherland and Engima were entirely believeable plots, owing to the level of research involved, The Ghost has a simply ridiculous plot about the CIA and the British Government and war crimes.
However, even though this book does have a ridiculous plot, I did enjoy it. It didn't really take much concentration to keep up with the plot and the characters have a bit of an edge to them that keeps you intersted as well.
Overall then, a decent read if you take the plot with a large pinch of salt.
