Once an uninhabited island off the Californian coast, the government used Morple to quarantine minorities during the sonoravirus pandemic from 2030 to 2045. At its conclusion Morple became the country's fifty-first state. This is where sisters Robin Karros' and Ariana Jackson's tragic journey began. As two of the first children officials checked into and raised in a state-run program responsible for inflicting severe abuse on Morple's youth, they shared hardships that strengthened their bond. After a social revolution put an end to the program and freed them, Robin and Ariana went their separate ways. Now that it is 2089 and each has achieved prosperity, their paths intersect after spending the latter portion of their lives apart. Even though it goes against protocol, Ariana reestablishes a relationship with her older sister and integrates with her family. In doing so, she risks her marriage and her husband's business interests, but it causes her to realize she must make up for her life's biggest mistake. It soon becomes apparent the fate of Robin, Ariana, and others has been more intertwined than they ever could have imagined.
