Call It What You Want by Brigid Kemmerer
Rob and Meagan both have reasons to hate going to school. Rob's is because of something his father did, and Meagan, because of something she did. Neither wants to have a partner for their math project, and as a result, they end up being stuck together. At first it is pretty rocky going, but soon they start to realize they have both misunderstood each other, and perhaps many others too. Can they find some common ground, and maybe help others in the process?
