It is a book dedicated to small strobes, specifically Nikon AND Canon flashes.
It has some very cool features, first there are only two chapters in the book, chapter one is "One Light" (25 one light setups) and chapter two is (you may have already guessed) "Two Lights" (20 two light setups), each image is accompanied with the "inspiration, how's, and whys" of the shot and a complete lighting diagram.
To make it as simple as possible to follow along the book is even color coded (Nikon - purple, Canon - green) so you can quickly and easily determine if the discussion is about a Nikon Speedlight or a Canon Speedlite.
Sandwiched in between each of the images are one and two page educational segments that start with the fundamentals of flash, inverse square law, mastering distance, characteristics of light, comprehending the direction of bounce flash, and so much more.
The authors also cover mixing speedlights with studio strobes.
This book is for all levels of photographers and the images cover just about anything you might ever want to photograph, still life, portraiture, corporate, commercial, architectural, and sports.
We learn to talk by listening to others, we learn to walk by watching others, and "Speedlights & Speedlites" is a great educational opportunity for those who want to "walk & talk" small strobes.
I could ramble on, but these pictures will give you a better idea than my words ever could, so below are sample pages of the image, the description, an educational segment, and the setup/diagram.
