'This masterpiece seemingly is an excellent math book saturated with lush insights and marvellous perspectives on Banach spaces. But start to read it. When furniture and people start to appear to you as diagrams you will realize that you are in the middle of a fascinating wildlife event.' Piotr Koszmider, Institute of Mathematics of the Polish Academy of Sciences
