The superb aliens-in-your-head SF sequel to the wildly popular The Rise
of Io, by the author of The Lives of Tao series.
When Ella Patel's mind was invaded by the Quasing alien Io, she was
dragged into the raging Prophus versus Genjix war. Despite her
reservations and Io's incompetence, the Prophus were determined to train
her as an agent. It didn't go well.
Expelled after just two years, Ella happily returned to con artistry and
bank robberies. But the Quasing war isn't done with them yet. The
Genjix's plan to contact their homeworld has reached a critical stage,
threatening all life on Earth. To complete the project they need Io's
knowledge - and he's in Ella's head - so now they're both being
hunted...again.
