Well! Things are finally heating up a bit. Excitement.
Not at first though. It's another Cecilia chapter and I have to say she's somewhat a bore. Perhaps because she is, herself, bored. Despite her minor delusions of grandeur, she is luckily getting smarter. After a lot of 'what dress to wear' and 'how to fix all the house's problems' she has a Clueless moment when she realizes her true feelings for Robbie. Perfection.
Unfortunately she also realizes in this moment that young Briony has read this strongly-worded letter. Uh oh. That cannot be good.
We also get further insight to the life of Leon in this chapter (and a bit in the short Briony chapter as well). His story is apparently to be told by those who idolize him. He appears to be a shallow, useless human being. It says something about his sisters that they worship him the way they do. It is concerning.
