Justine Saracen, The Sniper’s Kiss. Bold Strokes Books, 2017.
A romance novel involving women who love women set during WWII. A Russian-speaking American clerk in the Lend-Lease programme and a Russian soldier, later a sniper, encounter each other first during international meetings about the Lend-Lease programme. Later, the American clerk gets into trouble investigating corruption on the Russian end of the Lend-Lease problem and ends up at the front, where she disguises herself as a dead Russian sniper and partners with the live Russian sniper. Saracen has done her research: the WWII setting feels believable. The characters are reasonably well-rounded, the relationships make sense in context, and the writing is better than tolerable. As F/F romances go, it’s definitely in the top 10%, particularly for historical ones.
(I always feel sad judging F/F on these particular merits. But in any given month where I look at six or eight F/F books from Netgalley and at best only half of them are even readable, they are certainly the merits.)
Between the Devil and the Deep Blue Sea 
This may well be my fantasy book! WWII, women who fight (and investigate corruption!), and Americans having their Russian skills come in useful, lol.
I did think of you while I was reading it!
