Query: the best book i have read for some time

this was my first michael crichton book so i approached it with sceptisism. i was not dissappointed however as this had me gripped from start to finish.forced to write this review after reading the odd one or two give it 1 star out of 5. this is grossly unfair and deserves far far better. best book i have read in ages.i have since read "prey" by crichton and intend to purchase more of his books as they are geat reads.
