Aw, gaah! :( I love the First War setting here, and how despite the snippets of romance, you're not letting us forget that this is a war, and terrible things are happening. Poor Gideon. Poor Remus. :)
I might suggest putting a warning up for character death, though. It didn't bother me, but I'm me. :) It might be a shock for readers not quite equating "sad" with "brutal murder"? Just a thought.
