You may have seen comics by Aaron Caycedo-Kimura (aka INFJoe) portraying the life of an introvert: avoiding crowds, dealing with people who don't understand introversion, how introverts recharge or find happiness, etc. It was great to see he had come out with a book and I was happy to pick this up.
If you're new to introversion or want to learn more about it AND you're a visual learner I'd say this is a great pick. Interspersed with text and comics, INFJoe talks about what introversion is, what introverts do, and so on and so forth. If you're already familiar with the comics you might be disappointed since you've probably seen most of these online. But if you're looking for a guide or a short explainer for someone this might make a pretty good gift.
I wasn't quite sure what to expect when I bought this but I was happy to support a fellow introvert. There's not much more to say about this book since it's just a bunch of comics with a little text. It's somewhat similar to 'Introvert Doodles: An Illustrated Look at Introvert Life in an Extrovert World' by Maureen "Marzi" Wilson which I felt was more about introverts and introverted life in general.
I'd say if I had a criticism of it I suppose I was a bit disappointed by seeing so many of the same comics I've seen online and that I wish it were longer.
But if you know someone who wants to learn more about introverts and introversion as a topic and is a visual learner/like graphic novels this could be a great introduction. There's no plot like a GN, but if someone is not inclined to read a more text-heavy book (like Susan Cain's 'Quiet' for example) then this could be a great alternative. I bought this and was a bit disappointed because it's a bit pricey (I guess for the art and quality of the book itself) but it's not at my library and again I was happy to support the author.
