“A baby wasn’t an idea, as love was an idea. A baby was a fact. It was a being with a mind and a nature, and you could feel about it any way you liked, but a baby wouldn’t care. Just by existing, it demanded that you believe in a future: the future it would crawl in, walk in, live in. A baby was a piece of time; it was a promise you made that the world made back to you. A baby was the oldest deal there was, to go on living.”
– Justin Cronin, The Passage.

I’d forgotten about this passage from the book! The first two novels in this trilogy kept me up nights and haunted my dreams and yet I am anxiously awaiting the conclusion. Some of the writing in these books is just incredible.
