Carrier Strike by Hammel is a great account about the battle of Santa Cruz...I, too, have read Shattered Sword and would recommend it as well, although like I mentioned, to me, Santa Cruz is much more fascinating as the two sides traded body blows until one "left the ring"...
Midway may have been when the Japanese were stopped in their expansion and a certain degree of parity was achieved, but the Japanese could have very well sank the last operational carrier the Americans had in the Pacific at Santa Cruz had a few minor things gone the other way...
Aircrew losses for the Japanese were highest at Santa Cruz than in any other carrier battle...it was also the last time they were able to mount the classic "anvil and hammer" attack...
