Not bad for a beginner
I bought this book for my daughter, who received a digital SLR camera for college graduation and has no history of taking photos other than with an iPhone. I think it's a good introductory book as it covers the relevant topics of both cameras and photo taking in general, though there are probably better and more current books on the market. She's not a big reader, so the format is good for her as it demonstrates with actual photos and has short captions or descriptions of how to capture such effects. So, in that sense it's a good intro, but others who enjoy more detailed descriptions may find it a bit simplistic.
