The Energy Components Project: Book Two of the Time Sphere Chronicles

Newly beginning to time travel again after a huge battle nearly two years prior, vampires Vivian and Quentin uncover an unconscionable crime on a planet where life looks nothing like it does on Earth. Investigating it reveals a secret society operating across time and space, committing inhumane, unethical acts - and a mysterious figurehead everyone fears so much they only speak about her in hushes. What is the society? How does it operate? Who is pulling the strings? And why, and how, are their timelines twisted together? The answers to those questions force them to confront the darkest parts of humanity - and hard truths about Vivian's own path in the timeline.
