I'd strongly recommend Boris Chertok's "Rockets and People" - https://www.nasa.gov/connect/ebooks/rockets_people_vol1_detail.html https://www.nasa.gov/connect/ebooks/rockets_people_vol1_deta... . 4-volume first hand account (Chertok's immediate boss was Korolev and then Mishin, of N-1 fame, and Glushko, Energiya-Buran) . Really good memoirs about Soviet side of things.
