Everything Is A Game is a book of games that I wrote with Viviane Schwarz, published by Trapeze in 2022.

We pitched it in February 2020, and ended up doing most of the brainstorming and discussion while trudging around remotely in Red Dead Redemption 2.
I've written up a couple of the newly-invented games in more detail for the web:
I don't know that the little hardback book is still in print, but you can probably find it online and/or second-hand somewhere. It's also available as a cheap ebook.
