The most well known would be Kermit Roosevelt's "Countercoup" [1979], but its only intermittently reliable.

Kermit Roosevelt (Jr) was a grandson of Theodore Roosevelt, an OSS and then a CIA operative. He has a significant role in the coup against Mossadeq (though he's inclined to exaggerate his role and derring-do). The book was heavily edited for national security and political reasons, and so between reasons of vanity and raison d'etat, it's not reliable without checking against other sources. See The Strange Odyssey of Kermit Roosevelt's Countercoup for an account of the pre-publication history of this volume.

In terms of what the US was thinking at the time, the official Diplomatic History series Foreign Relations of the United States a few years ago released a volume on relations with Iran in the early 1950s which includes lots of formerly classified material where the US develops its position on Iran. This is what I'd read first.
