From a historian perspective, this book is amazing because diaries about the everyday life of an average person are hard to find. From a reader perspective, this book dragged considerably and it took me a solid 3 weeks to finish its 166 pages. It's not exciting in any way--it details Emily's moves around Colorado to new jobs, her time at those jobs (mostly housekeeping positions), and her issues with her children and ex-husband. She's also extremely religious, starting each entry with a Bible verse.
Can't say I recommend it, unless you have a strong interest in diaries and/or women in the West.
