You may be interested in looking over the AH booklist, linked is the section for the Pacific War if you are interested in more on that subject.

Of special note is Hasegawa's Racing the Enemy which also examines the end of the war in the Summer of 1945, with particular attention to the triangular relations between Japan, the US, and the USSR. With a key topic being the importance of the Soviet Union's actual entry into the war on the timing of surrender in the middle of August.
