I purchased the book after reading a number of accounts of the battle of Cannae contained in more extensive studies of Hannibal. However, in each case I was disappointed with the discussion of Cannae. Healy's book was not a disappointment. Especially appealing were the maps which accompanied the prose. What little that was missing in the verbal description was more than made up for in the maps.
After finishing the book, I felt that I understood the tactics and strategy that were both planned for and carried out. This is an excellent book and I would highly recommend it.
