This is the type of novel I love - great, high-concept premise, relatable characters, unique structure and storytelling. And it's SO different than the Chaos Walking series (which I also adored) so plus points for that too.
Let's start with the premise. Basically, Ness pokes fun at the "chosen one" trope by making his protagonist just an ordinary guy who lives in an extraordinary town. Mikey is not an "indie kid" so he doesn't have to worry about being the one who is essential to fighting off demons or vampires. He has his own stuff going on: his sister has an eating disorder, his dad is an alcoholic, his mom is running for office, and he has OCD and is in love with a friend of his.
So structure-wise, there's a short run-down at the start of each chapter telling us what is happening in the "main plot" and then Mikey tells us what's going on in his life for the rest of the chapter - and it's clearly much more interesting and authentic.
I love the underlying theme of being the hero of your own story, and I rooted for Mikey the entire novel.
You'll enjoy this if you like meta-fiction, originality and gentle satire.
