4 out of 5 stars
Alone is very different than the other books by Gardner I read in the past. There are lots of twists and turns and at some points I really didn't know who the good guys or the bad guys were.
I found the beginning to be a little slow, but the pace in the last third of the book really picks up and it was hard to put down. Even when it was getting late and I had to sleep it was hard to put down!
I would definitely recommend this for fans of suspense!
