This is the website for the book, Practical Go: Building Scalable Network and Non-Network Applications, written by Amit Saha and published by Wiley in mid-December, 2021.
You can have a look at a detailed table of contents, download the source and look at support for resources that may have been referred to in the book or simply additional relevant pointers.
Of course, if you like the look of it (I think you might!), you can buy a copy using one of the sellers listed on the buy page. The first chapter is available from the publisher here.
