I need help finding this book for my sister she is starting college again next week and she needs this book but has no money to get it.

Developing Person (Life Span)

Thats the book she needs. I have been looking on the internet for a while now and no luck yet will keep looking but i figured may be some one knew where to get it or knew how to get it free or could help in my quest to find this book that would be awesome. Thanks
