The Star Children by Rachel Deagan
They were called The Star Children, created by The Project with their own special abilities; a mix of “races” to bring the world to a new consciousness. In order to save the world, Jacey has to die, but two allies stand by her side. Unaware at first of what she and her newfound friends are, she begins to discover her entire life was a lie. Now the three are being hunted as worlds and planes of existence collide.
