This opens so strong with the dinner table, the food shortage. The descriptive tone you take works well with the mystery you open to. You hold the cards close to your chest right until the end, and it works really well. You drop tipbits in that hint, without giving anything away. The one a day bit works really well for that, I ended up wondered how they could maintain that as the characters did. The mother's emotional dilemma is really well framed, the impossibility of asking people to give their own lives instead of give up. Then how it ties into the block chain is a really fun touch, for it to wind back to a classroom, it felt a very fitting story to be reading on the block chain. Thank you very much!!
