For book forty three of 2015, I enjoyed the book The 33 Strategies of War.
I’ll just come right out and say it; this book was awesome! It covers all of the ages of war and provides the strategy of key historic figures which were extremely successful in war. It then further covers how they applied the specific war strategy through execution of the strategy through the operational and tactical levels of war.
This book is one of the top contenders for 2015; highly recommended.
