Nerd Do Well by Simon Pegg
I knocked it down a star because...well...I just didn't like the sci-fi story. Pegg intersperses his memoir's chapters with brief interludes of a fictional sci-fi story that features a remarkably similar Simon Pegg. The story started out entertaining and humorous, but I just lost interest as the story wore on. It almost felt like the sci-fi story was just filler to make the book a little thicker.
If you are a self-avowed geek/nerd/Simon Pegg fan/whatever then definitely give this book a whirl. I'd recommend the audiobook version simply because of the narration...it's almost like a prolonged narration like you would hear in one of Pegg's movies like Shaun of the Dead.
