Generally satisfying, though not the end I’d have wanted. Also a couple of disconnects. All the stated evidence was that the ship had been buried ~300 years, but the characters decided it was only 50 years departed and must have traveled back in time about 350 years. They assumed dates on equipment (did/mm/yy) had to be 50 years in the future; but just as easily they could have been multiple centuries in the future because the first 2 digits of the year were not a matter of discovered record.

Incredible read. My first Crichton and definitely not my last.

I kind of got twist-and-turn fatigue towards the last third of the book. For me I think the forward motion in the beginning was more enjoyable than the ending, which felt a little overwrought to me. The first part of the book had me looking forward to a horror sci-fi romp a la Alien or Predator but what it ended up being was more of a speculative fiction action story with some hit or miss character drama. I wish he didn’t tease me with an ominous and foreboding first half if he wasn’t going to deliver on the scares later on. The book was very easy to read and keeps your interest. Overall decent pop fiction.

Not my fave book of his but still an interesting story. A difficult story to write for anyone I enjoyed it

I have read 5 of Crichton’s works. Timeline and Congo being my favourites. This is by far the least imaginative and most predictable. The psychological theme in this book is an absolute fail. Spoiler alert, the “We will decide to forget” ending. What a joke!

The sphere is a great book, I’ve read more then once, the mix of humor, plot, fear, that goes on in that book is phenomenal. Signed, Dr. Mo Rosen P.H.D.

Always the unexpected

Sphere is brilliant. It executes the thought of intelligent life elsewhere and suggests the allure of contact to such life undeniable in our current form. Eventually, asking if the "super-ego"can be taken from such meeting. A sort of precursor in selflessness necessary to make the stride for understanding. Unlocked to the highest intellectual bidder the sphere conquers human intellect. Ultimately, demonstrating our species inability to control an emotional intellect necessary in such aforementioned meeting while also questioning our ability to cope in high stress environments. Sphere forces a reflection, asking if we are even ready. Then it is gone.

It was the best book I've ever read it was fast paced and when things seem to add up more things get uncovered

One of the best books I've ever read, and an excellent and deep exploration of human motivations at the same time. In my social work program we weren't even taught material as deep as this work of fiction. Crichton hits another home run. You could randomly select any of his books from the library shelf and take home one of the most enjoyable books you'll ever read. This book explores the underlying motivations and unconscious reasoning behind the characters' tense and anxious moments underwater. The premise of the book is exciting enough, and there is suspense throughout, but when it comes to exploring these characters' emotional content, Crichton comes out on top. One wonders as to his scientific background, because for a medical doctor, he has an acute understanding of the human mind. This book will keep readers on the edge of their seat regardless if they appreciate subtleties of character development. Recommended to readers of all ages! Enjoy!
