Ok so I let my friends borrow this book of mine, it was a field guide about $20, and someone stole it. They said they would buy me a new one and they never did. I need this field guide soon in about a week and I'm at a lost. Should I insist on a new book, or just buy another one. Also, I'm friends with both of their whole families which only adds to the awkwardness. What should I do?
