It is fascinating how the human brain will work to make sense of the world around it. When only given a few pieces of information in a specific context, your brain will work to fill in the gaps. For example, you see a tall green triangle in the distance and can't quite make it out, but you know it's late December, so you may be inclined to assume it's a Christmas tree.

This type of 'confirmation bias,' and how it can cloud our perceptions of people, is exemplified with the narrator's story of Cassie. The fair-haired girl has a mystery about her, she is not necessarily forthcoming with her innermost thoughts, and so different people interpret who she is very differently, given the context in which they have come to know Cassie.

While the entire book is the narrator's summary of her most significant time spent with Cassie, the reader is still left not fully knowing who Cassie really is. The characters of the book do not seem to know who she is either. The people of this town are more wrapped up in the story or myth of Cassie than the reality, the same being true of the two friends who most cared about her.

This was a captivating narrative, delivered with a vivid, yet straightforward prose. Would recommend.
