If you like the perks of being a Wallflower, you'll like this book. It follows a man dealing with the death of his younger brother and how his mental health deteriorates over time, leading to increasingly unhinged behaviour. 

I think Filer does a very good job presenting the passage of time using different fonts to signify changes in location and medium. Because it is written from the perspective of the person going through it, I think the mental illnesses are portrayed in a very good way; how they are not 'solvable' but are able to be managed, how they blend with someone's personality because they are a part of him. It's very good.
