Query: Unbelievable

I thought this book was awful. Louis Begley's decision not to use quotation marks in his character's dialogue made reading it a chore. His character development was superficial and his attempts to describe what motivated each character were obvious and ineffective. I didn't relate or sympathize with any character and found most of their actions implausible. The ending was ridiculously unbelievable. The only good thing was that the book is short. Hopefully the movie will be a vast improvement.
