Attachments is my second book to read for Rainbow Rowell. Rowell certainly has a way of writing about cute people (cute in character). As a copyeditor myself I found the lives of Jennifer and Beth very interesting, to know people who care about punctuation and writing correct grammar, cuz we are a rare breed (but of course that's not all). What I did not like was how easy the ending was, just so easy and unrealistic. Although if I probably was in his shoes I would have done the same thing. I know I would not forgive someone for reading private messages between me and my bestfriend easily. 
 The idea of falling in love with a woman through her writing, personality, jokes, and so forth is kind of raising the bar a little bit for us guys and doesn't happen too often (although it happened to me before). But it is not fiction though, just incredibly rare. 
 Overall, it deserves a 3/5 rating. And I would recommend it to people if you like reading something light and funny, just to pass the time.
