I originally bought the first three of the Bourne books as a result of my great liking of the new films of the same name; indeed, I have always been under the impression that a greater appreciation of a given story can be attained from the reading of a book than its corresponding film. Suffice to say I adored the first two novels - Identity and Supremacy - but somehow felt that the third of the series lacked a little something.
I nearly refrained from purchasing the Van Lustbader Bourne books from fear that they would be nothing more than stretching the story, as is not unheard of within television shows these days. But upon reading The Bourne Betrayal I found that this was by no means the case: I found the story to be absolutely fantastic! A brilliantly written and immersive spy-thriller, with a substantial, and what I believe to be inspired, twist in the plot.
I have noticed some of my fellow reviewers expressing dissappointment in the techniques and style with which the book was written, which is their prerogative, but personally I would argue that these are merely a result of a new author, and though it is true that certain differences can be noticed I feel that - yes, the style of the writing features a few differences from the originals, but further that Van Lustbader's take on the story of Jason Bourne is superb in its own right and ever remains true to the original novels.
An excellent read :)
