Untamed ($17, originally $28) by Glennon Doyle just came out this year, but it's already on my "greatest of all time" list. The book is a powerful manifesto on creating a life you want, and embracing all that you are. After reading it, I sent it to my best girlfriends, because I think it should be required reading. It's also written in little vignettes, so it's easy to just open a page and get some magic.
