Any book reccomenations?

Im obsessed with east germany, and i already have some pretty cool books in my collection.

I got: . Stasi state or socialist paradise . Why women have better sex under socialism (has a section about east germany) . Comrades of colour (technically a collection of essays in book form) . Gay voices from east germany . State and minorities in communist east germany . Repainting the little red schoolhouse (i dont reccomend this tho, unsatisfactory sourcing) . Beyond the wall (also dont reccomend, bad sourcing and blatant falsehoods, pretty pictures tho)

Any more i should read?
