Jacob Have I Loved is a great book for any child that resents their siblings, because that?s how this twin sister relationship is best described. Sara Louise recalls her difficult adolescence on Rass Island and her intense jealousy of her own twin sister Caroline. Caroline is a selfish, over protected person and Sara Louise feels like her life is based on competing with the most admired sister Caroline. Caroline always got what she wanted and was considered to be the attractive one, smarter one by her mother and grandmother. Foe example one day before attending church when Sara Louise unexpectedly ?became a woman? she stained her Sunday dress and couldn?t go to church, her grandmother had a cocky attitude because she couldn?t attend church that day. But when Caroline had her period she was congratulated That?s just many of the trails that made Sara Louise stronger throughout the book.Caroline is assumed to be the better sister, but in reality Sara Louise is the independent and strong sister, she never let anything stand in her way. When Caroline needs other people for almost every thing and is surprised when she doesn?t get her way. For example, Sara Louise and her best friend Call, Call thought Caroline was attractive but rarely played with her. He liked Sara Louise?s personality, she wasn?t fake and didn?t pretend to be someone she?s not. But when Call came back married to Caroline from the war, all of Sara Louise?s dreams were lost, but still remained friends with Call and kept going on and on. Yet another example of Sara Louise?s strengths.This book emphasizes with Sara Louise and helped me see her point of view and better understand that all people have their own talents that they may not have discovered yet. This twin sister relationship was based off of jealousy and beauty that would have never have been if they were both treated equally and their mother and grandmother didn?t play favorites.
