I just recently finished the book "A Mouthful of Air" written by Amy Koppelman. As many of the reviewers on Amazon said, "I couldn't put it down" either.

Having dealt with depression off and on over the past 20 years, and having had moments of postpartum depression with at least 4 of my 5 pregnancies, I found it easy to empathize with the main character. The fact that she was young and rich and living in NYC didn't make me feel her pain any less.

What with all the fuss about "The Lovely Bones" over the past year or so, I'd recommend this novel over that one any day.

Word to the wise, though...have a hankie ready if you do pick it up! because you won't be able to put it down and you'll need it, sooner or later.
