"Atonement" is the story of thirteen year old Briony and her misunderstanding of the world. It begins in the Tallis household in 1935. Obsessed with fantasy and books, she sees sinister motivations in the blossoming romance between her sister and the son of the family's house cleaner. When something terrible happens, Briony makes a mistake that will change the lives of everyone around her.
The characters in this story are all well developed, but Briony is the stand out in this regard. Her motivations straddle the line between clearly defined and mysterious. She has a clearly defined character, dramatic, self centered, and eager to please. Cecilia and Robbie are less defined, but still sympatheic and interesting. I found Robbie slightly unpleasant in the second half of the book, but it was understandable considering the circumstances.
The plot cannot be properly discussed without getting into spoilers. However, it unfolds in a clear manner. All the plot points are set up before they happen, and given proper foreshadowing. At the end, there is a plot twist. Since I highly recommend this book, I will not be spoiling the twist. However, I will say that it makes everything else that happened in the book unclear (in the best possible way).
This book contains a depiction of rape, extreme violence, and rather gruesome hospital scenes. If any of these subjects upset you, I would not recommend this book. If you are able to handle these topics, and you appricate books that focus on pyschology and character exploration, I would definitely recommend this book.
