The Girls by Lori Lansens

This is the story of Ruby and Rose, conjoined twins who were abandoned by their birth mother and adopted by the nurse who delivered them. As they approach their 30th birthday, Rose, who has aspirations to be a writer decides that the time is right to tell their story. Ruby, who is less academic finds this process tiresome, but also decides to add her own version of events. The girls make a deal not to read each others writing and so the book is told by two people, who are joined as one, but have two different versions and recollections of the 'truth'. This is a warm novel, which explores human nature, love and relationships as much as it looks at the lives of these unusual siblings.
