Gretchen Rubin's next book, Happier At Home, hits stores September 4, 2012!
This is one book that I am excited to read. I have read, loved and recommended The Happiness Project. You can find my review of it here.
You can check out Gretchen's blog over here, where she has daily posts about the quest for happiness and related topics. I find it a great resource with my quest for a better and happier life.
