Wings of the Malvinas by Santiago Rivas.
A fascinating and well detailed book with 400 pages packed with information/orders of battle of both sides and many previously unpublished pictures.
This book tells the story from the Argentinian side and even though I'm only a quarter the way through it I have changed one or two opinions I used to have.
