Nara just lost her job at the Human Intelligence Agency. She didn't expect to lose her sense of control next.
Keeping a chained Martian prince in her basement was supposed to buy her answers, not new problems. Vile, the Power Prince of Mars, wants one thing: the power his father lost to humans years ago, power that may be living inside Nara herself. When his first attempt to prove his usefulness ends with an innocent man turned into a ten foot monster, Nara has to decide how far she's willing to go to control a force she barely understands.
Her ex-coworker Deaton is still loyal. Her younger brother Rail wants the truth. The agency that fired her hasn't stopped watching. And the secrets buried in "the Lab" run deeper than Nara ever let herself believe, secrets that put the man she called Gramps in a very different light.
When Nara and Vile are pulled into a shared astral plane and forced to face the fears that shaped them both, the line between captor and ally starts to blur.
Fusion picks up where Superior I left off and pushes the story further: family, trust, and the price of power, set against an alien standoff that gets more complicated with every page.
