Full disclosure: this book was written by someone I know socially. I'm pretty sure I would have enjoyed it just as much if I'd found it by chance, but the sneaky thing about biases is how invisible they can be.

The description pretty much says as much as I can about the plot without spoilers. But what I can add is that Colin manages to be simultaneously terrible and very, very relatable - all the weaknesses that drive his series of bad decisions are ones everyone shares to a greater or lesser degree. And with that, I feel like the book manages to be a bit more than the knowingly silly light read it presents itself as, because the protagonist is a case study in how some less outlandish real world bad decisions happen. But this never comes at the expense of it being light entertainment.

Minor criticisms: even the other characters who get significant time don't feel fully fleshed out, probably because we only see them through Colin's eyes. And there are times, particularly towards the end, when the fantasy elements can get a bit USS Make Shit Up. Which would be very frustrating if the point of the book were Serious Fantasy Worldbuilding, but it's so not that.
