An engaging memoir, mixing summaries of scientific research into shyness with anecdotes and memoir from her life. There's a lot to like here - Prior is ruthless about her own issues and clear-eyed about the ways in which she's made her life work around her chronic shyness. The book pivots on her break-up with her long-term boyfriend, leaving her without the social crutch that he represents. It's not always easy to completely believe Prior's issues given all the amazing things she's achieved, but she writes well and provides real insight into living with social anxiety. ( )
