What should I do?! I need ideas.?

To make a long story short..A few months ago my best friend slept with my now ex behind my back. Because of that I've refused 2 talk or have any dealings with her for the past 3 months. All of a sudden on Christmas I get 2 surprise Christmas presents on my doorstep . One was a pink pj set, the other gift which really got my attention was a book titled " God don't like ugly". I think she was trying 2 be sarcastic with the book, I felt I should of been the one giving that 2 her.But, anyways my question is. What should I get her? I've been on various websites trying 2 find a book reflecting a best friends betrayal but I can't find any. Does anyone know of any or have any other ideas?
