I get you're sad but to be honest I only feel a little bad for Sera. It's like the girl from Hunger Games 2 that jumped in front of the monkey to save Peta. Maybe Milla and Sera were close but I just don't think the author built up that relationship enough to feel bad. Plus, like I said in the first book review, I didn't trust Sera at all. Her saving Milla shocked me.
