To put it as simply as possible, Sphere is one of those books that once you pick up, you won't put it down. Chricton's style of writing leaves the reader constantly wanting to "see what happens next." He entices us with incredibly vivid imagery. Chricton is like the rider of a mule, who is hanging a carrot out in front of the mule. The reader is the mule, always pushing forward. Excellent book.
