Honestly, I guess I thought The Book of Knowing would be different than The Book of Overthinking. I read and liked The Book of Overthinking so I'm going with the same rating for The Book of Knowing because it is so very similar. The same ideas are presented in both books, aimed at different age groups it seems. (I don't remember many/ any curses in The Book of Knowing but I thought they were well-placed in The Book of Overthinking so I liked the impact of them there)
I found several great tidbits and processes to deal with worrisome overthinking detailed throughout both books.

Loved the narration. The narrator was great and placed valid emphasis where needed.
If possible I'd 100% recommend everyone take a look at the ebooks/ hard copy books because of the amazing, humorous illustrations!

Thank you to the publisher and Netgalley for this advance listen copy.
