Not my best read, although it is the first book I've ever read on a comic book character. I'd heard a lot about it and I thought, why not? So, I felt like Natasha wasn't not always quite in character according to my skewed perception of her as played by Scarlet Johannson. She was too... friendly?...with Stark. Not that she can't have friends, but at times their relationship was basically playful and that didn't fit with the idea I have of Black Widow. The plot was well written though and the characters realistic and well constructed. Near the end, the whole Alex incident shocked me. I really didn't see it coming and I broke me a little. Although it makes sense in a way I guess.
