Need help with a title

[Amanda]

This is not strictly mystery, but it's the only group I'm in and it seems like youall read a lot, so I'm asking for help.

A novel came out a while back about a couple who are not getting along at all. Each of them thinks the other died in the World Trade Centers on 09/11/01. In the first chapter they both have to conceal from the people around them that their first reaction to the tragedy is glee that their spouse is dead.

Sound familiar? I need a title. I read the first bit of the book and want to get it and finish it.
