" Their world will eat at you," Mab said. "Strip you away bit by bit. Cut off from the Nevernever, you will not survive. Whether it takes one mortal year or a thousand, you will gradually fade away, until you simply cease to exist." Mab stepped closer, pointing at me with the scepter. "She will die, Ash. She is only human. She will grow old, wither and die, and her soul will flee to a place you cannot follow. And then, you will be left to wander the mortal world alone, until you yourself are only a memory.And after that-" the queen opened her empty fist "-nothing. Forever. "
