I have three books that are international editions, that are just a pain to sell back. They are exactly the same for what you need for class and are all in good condition, with some highlighting in them.
The first is Life-Span Development: A Psychosocial Approach by Newman and Newman. It is the 11th Edition. This is for Professor Radis' Life Cycle class
The second is Psychological Science 3rd Edition for Psych 101.
The third is Adolescence 13th Edition by John W. Santrock, which is for Adolescent Development.
Just email me an offer!
