Theo Goodwin is used to running, while Gemma Roberts wants nothing more than to find somewhere to call home-someplace to belong. With the threat of the Authorities looming, despite their strange connection and a shared desire to protect their family, a compromise between fight or flight is no easy feat. As they traverse a new shared life together, they must learn to understand one another for the survival of not only themselves but also those they hold dear.

When a new group swoops in with their own unique powers and motivations that threaten to ruin everything Theo and Gemma have worked toward, the invitation into their broader community has its appeals but equal drawbacks. Tension simmers within their crew, testing their bonds and questioning their unity. As they navigate this delicate balance, they'll discover the world isn't what it seems and finally put a word to what they are-mutants. More are found every day, with abilities far beyond what they thought possible. And the Authorities are doing more than hunting them down.

With mutants on the precipice of war with the government, will they decide to join the cause and fight or continue to run and hide?
