The twins Carlie and Steph were identical at everything. Appearance, music, books, food, clothes, movies... everything. At first, everything was awesome, I mean, how much more perfect can it be when you have just another you who totally understands everything about you? Except, nothing was perfect. Not after the inseperable twins were separated. Not after other people had come into their shared life. Not after the problem they'd thought was big became small. Not after those two, who were once exactly the same, became total opposites...
