I want some sweet things to write to my Russian boyfriend while I am away in Berlin. He got really excited when I accidentally found a phrase referencing to some song about a soldier so the more specific the phrase is to Russian pop culture/life the better. In cyrillic too if possible would be best. Thank you in advance!!!

I am looking for a book to read. after just completing Call of Duty World at War I would like to learn a bit more a bought the russian front. Preferably from the point of view of a russian solider and from the time era like from Stalingrad to the capture of Berlin.
