I'm an 1800 rated player. This book may sound, from the title, like just another book of puzzles, but it's nothing like that. It's a genuine organized tactics course, with good explanations of each position. The positions are grouped by theme so that after a few pages in each theme you are really learning what to look for. You can tell a lot of work has gone into the excellent selections and the clear comments on each position. The chapters are headed: Rook, Queen, Bishop, Knight, Pawn, Two Rooks, Rook & Bishop, Rook & Knight, Two Bishops, Two Knights, Bishop and Knight, Queen and Bishop, Queen and Knight, and Three Pieces.
I own several hundred chess books, and have enjoyed them all, but I don't hesitate to say that this is one of the best in my library, which is why I'm taking the time to recommend it. Considering that this book is selling for under $15, it's truly a steal. But it's a great book regardless of price. If you want to improve at chess, get this book. You'll be impressed.
