This is indeed a great book if you are looking for some thrills . The author successfully mixed reality with fantasy together and mixed in some science . The book was really interesting and I was truly surprised by the ending . The only reason I didn't give this book a five star is because the thrill part wasn't really there , which was rather disappointing . It somehow turned in to action than mystery when he jumped off the building , which is what made this book worse .
A re-read from many years ago....the idea is really frightening, esp. when that happened some months ago in this city, but of course, that did not "penetrate" the top of the building!
Interesting story but some questions left unanswered. I think the ending could have been a lot better and he could have played with the time difference aspect a lot more but he didn't hence the 3 stars.
