I feel kind of numb, I just finished reading it and just stared at the last few lines.
But I have to admit after reading the last lines my first thought was Alina but dismissed that because Mac saw her dead. Her dad, IDK..during the coversation between her parents she overheard it was said that he got so sick even trying to go check on her so how could it be him? And she hasn't even admitted to herself yet how important Barrons is to her so I'm just lost as to who it could be that she felt she had lost everything. Unless it was a moment of truth and it was Barrons and she realized what she lost. But if it was him then my happy ending just went poof!
