Tiara had given her cells to the Zeta Reticulans and the alternate Earth human-alien greys for the last time. She'd had enough. She was going to have her hybrid human-alien baby, and there was nothing they could do to stop her. However, she had no idea that her cruise ship, the Zeta's IFO and the Space Military IFO would merge and shift to a template level reality, then generate a massive gravity beam across space and time that pulled comets to Earth. How were they going to separate two saucer-shaped space ships from the cruise ship before they were crushed under the contracting metal? How were they going to get back to Earth from the template level reality before its nothingness dissolved them? And what had the aliens planted in Tiara's head that could explode at any moment? Can Tiara work together with the humans, the alternate human-aliens, the Zeta Reticulans, several conscious spaceships, and a group of Alien Characters, to help save the Earth from being destroyed by comets? Find out in Tiara and the Comet Apocalypse. Book #3 in the Galactic Missions series.
