“ Izzi: Remember Moses Morales? Tom Verde: Who? Izzi: The Mayan guide I told you about. Tom Verde: From your trip. Izzi: Yeah. The last night I was with him, he told me about his father, who had died. Well Moses wouldn't believe it. Tom Verde: Izzi... Izzi: [embraces Tom] No, no. Listen, listen. He said that if they dug his father's body up, it would be gone. They planted a seed over his grave. The seed became a tree. Moses said his father became a part of that tree. He grew into the wood, into the bloom. And when a sparrow ate the tree's fruit, his father flew with the birds. He said... death was his father's road to awe. That's what he called it. The road to awe. Now, I've been trying to write the last chapter and I haven't been able to get that out of my head! Tom Verde: Why are you telling me this? Izzi: I'm not afraid anymore, Tommy. ”
