Shadow of the Coalition - The Omni Towers, #2

Only in the darkness can vengeance thrive.It's been a month since Kayla, a headstrong ruin rat, and Carl, an OmniLab trader, returned to the surface. After she helped to restore control of the towers to those who would look after the best interests of the people, she'd found herself irrevocably bonded to Alec, the new co-leader of the High Council. Although her heart belongs to Carl, she finds it difficult to resist the strange bond between her and Alec.
Caught between learning how to handle her new emerging abilities, mysterious earthquakes, and a strange group seemingly intent on targeting OmniLab, Kayla is once again swept up in events that threaten to change the entire future of the towers.
