The first book is Bossypants by Tina Fey. I may have loved this book because 30 Rock is one of my favorite TV shows or because she is AWESOME. Her humor is right up my alley and I feel that I can relate to her geeky awesomeness. I tried to convince DH that Tina and I were similar but he didn't agree. Even the cover is pure genius.
The next two books were murders, everyone ends up dead books but good mysteries. I read them late at night in a house with open doors and windows on a small island with no one around so I scared the hell out of myself. The first one was Every Last One by Anna Quindlen about a "perfect" family told from the mother of three teenagers point of view. The unthinkable happens and how she deals.
The second scary book, Dark Places by Gillian Flynn was a nice deviation in that the narrator starts off the book by saying she is a bad person so you can get past the "sadness" of her story and focus on the characters in a whodunit book. A good mystery without all of the slasher details.
