Final Revenge [Book 3 of Obsidian]

[Book 3] Morgrim Star is dead. Becky Weed has survived the Blood Games. The four remaining friends have escaped the island of the Unnatural and gone up into space before they were killed. They think they can just simply land back on Earth and rebuild civilization and repopulate. Just as they think Morgrim is really dead, he's formulating a plan to escape the deciverse of Death, where everyone goes when they die. He's only making it worse by brainwashing the remaining group's friends, Shawn Williams, Shannon Cheula, Keely Harmon, and Griffon Sonalo. With them under Morgrim's command, what chance do the other four have against him? What are they going to do when he escapes the deciverse and hunts them down? This time, his final goal is to kill all of them. There's no universe to worry about for him anymore. How are they going to get rid of Morgrim once and for all?
