If you speak English - Soyuz User's Manual (very easy to google). It is a detailed description of the Soyuz launch vehicle. There are also many textbooks on this topic, one of them is "Design and design of rocketry equipment". But, again, not without a fly in the ointment - it contains many formulas.
Deputy Korolev B.E. Chertok wrote a wonderful four-volume "Rockets and People". I recommend to everyone interested in the basics of rocketry and the history of the Soviet space program.
