Grip of the Shadow Plague (Fablehaven, #3)

by Brandon Mull

Our beliefs don’t always harmonize with our instincts, and our behavior doesn’t always reflect our beliefs. We constantly struggle with right and wrong. We wage war between the person we are and the person we hope to become. We have a lot of practice wrestling with ourselves. As a result, compared to magical creatures, we humans are much more able to suppress our natural inclinations in order to deliberately choose our identities.”
