The Keeper approaches his creation cautiously and pokes it with a long, black fingernail.

Embossed in gold on the once-smooth cover is the title, "Cassandra's Sleepy Time Tales."

He runs his fingertips lightly over the words, then lifts the book and tenderly presses it to his chest, rocking it back and forth like a newborn baby.

"Happy, happy birthday, my little one. You will save our planet. You, and the other, soon to be born."

Once again, the Keeper begins to sing.
