My god, that was sad. It's not really a romance, more a tale of frustrated desire wrapped up in an indictment of the First World War, and it's beautifully done. It's a very understated novel; Boyne manages to capture the horror and despair of the trenches very clearly and without trying too hard to be graphic or shocking. I felt great empathy towards his characters, despite (or maybe because of) their flaws. I'm not sure if 'enjoyed' is the right word to use, but I read it start to finish without reading anything in between, so it has to be good. But certainly it's one of those novels where, right from the very start, you know it can't end well.
