I love this whole series, but especially this book. Penelope is a friend of one of the sisters and the whole family. She's always had a love/crush for Colin but knew that it would never happen. Her plump and plan self would never attract him. Colin never really looked at Penelope until this book. He was avoiding his own family due to some personal conflicts (he didn't think that he good at anything and didn't have career/accomplishments - Middle son syndrome). He was able to talk to Penelope and she gave him some sound advice. This is when he started to view her as more than just a friend (or friend of the family). He realized how smart and pretty she is. There are some surprises and secrets that Penelope had of her own and there are many cute/funny parts.I loved it!!!!
