I'm a bit surprised by the other reviews. Clearly Miranda is the hybrid child of Amelia and her father Greg, a SeaWalker. She is the bridge between the two races. She will bring the two together. What is the mystery is who controls the SeaWalker race? The sea walkers are definitely afraid of who that being is. They do not have free will. The battle is set for a new order. I'll be curious to see what the sequels provide.
