I've always been interested in utopian and self-governing communities and I find the Kibbutz movement in Israel and the sort of utopian socialist idealism attached to it as a fascinating contrast to the more hard-headed and religious nature of the modern Israeli state, especially considering the influence the movement had on the politics and military affairs of the 1940-70s era of the countries history.
I've looked around and most books that are widely available seem to be memoirs of growing up in a kibbutz which while interesting is not really what I'm looking for, I'd much rather a history that looks at the ideals and roots of the movement, how it grew and why it petered out.
It's a bit of a niche subject so maybe there is an overall history of Israel that has good coverage of it?
If you're interested in the economic history of the Kibbutz, Ran Abramitzky has a book on the topic: The Mystery of the Kibbutz: Egalitarian Principles in a Capitalist World. It's mostly an analysis of how and why Kibbutzim ever worked at all, given their radical economic model, and how they have survived and adapted to the pressures of being a non-market society embedded in a market economy. It also has some element of personal and family reflection, but it isn't a memoir.
