The title of this book ended up being rather prophetic. It was a hot mess and lacking in any reason. I wasn't underwhelmed by this book so much as I was left wondering what the hell I had just read. A Mess of Reason lacks strong and cohesive characterization and fantasy, not realism, underpins it.
Scout and Tess have been best friends forever and somehow both are in love with each other and neither is willing to make the first move. Sounds like a great NA plot, right? Except they are 29! The level of NA angst in these 29 years olds is insane and disappointing. At 29, a little maturity would be nice. A spine would be awesome.
Scout's a rock star, btw, in case you missed it. Because that's not in the book at all. What he is is a digital guy who does "concerts via hologram" thanks to Tess. Sorry, no dice! Give me a real rock star who deals with real rock star stuff. And Scout, really? Total fantasy-land character. He's not even remotely written with real life in mind. We deserve better than that.
As for Tess, the woman who masquerades as a college kid needed therapy years ago and somehow never got it. A shame really, because not only did she need it but it would have solved half the problems in this book. And Tess is the most inconsistent of the characters in this book. She goes from self-pity about never hooking up with Scout because she's afraid to ruin their friendship to actively refusing a relationship with him because reasons (spoilers) and party of that is that she never wants a full and complete loving relationship. Seriously? Bait and switch a little?
And, after all of that, then we get the "big misunderstanding"! Ugh! Just ugh! It was so unnecessary. This was a book with inconsistent characterization and a mess of a plot.
