Great characters, plot, resolution. One of the best mystery/suspense books I've read. There is everything you want. 
 There is great 'literay' style phrases and thoughts that get you laughing. The atmosphere is pure suffocating anxiety when the narrator is "Patty". 
 This is a mystery, but it doesn't present the mystery features like a standard mystery. There's not an endless list of characters or complicated back stories. There are flashbacks but it is all necessary. 
 It is rare to find a book that builds-up a great story and delivers so well.

 I reread this after almost 7 years and it is frightening-not just because of the story but because of how little I could remember. I'm amazed I could forget so many details of a book this captivating. I could remember few of the details and was really fuzzy on even the plot. It was a great read again so at least I could remember that but it still is shocking how terrible my memory is compared to my confidence of it. 
 The plot, structure, characters, dark humor, and writing are all great. The story if written today would probably need to mention all true-crime podcasts that have sprung up since Serial, not that Libby would be listening to NPR.
