In the second book of this adult science-fiction thriller, a young immigrant woman, from Colony Three, becomes an outcast within Eden's class system but decides to retaliate, and she aims to recruit Randal Scott, one of the colonies' liberators, into a social-justice organization involved in a shadow war against murderous extremists scheming to preserve the status quo. What is the journey of a lottery beneficiary, a colony immigrant, like? What happens when an immigrant is transplanted on Eden, the utopian motherworld of humanity's intergalactic republic, with hopes and dreams only to find themselves still marginalized by a class system? Akane Sugimori, a nineteen-year-old immigrant, found out, suffering through one tragedy after another. Akane fortunately survived the hardships of Eden's class system and now attempts to recruit Randal Scott, one of the colonies' liberators, into a social-justice organization fighting for immigrant equality. Randy seems to be the perfect prospect, now finding himself a pariah among his brothers and sisters-in-arms since siding with the Coalition and taking part in the Battle of the Quad. But Randy discovers there's more to this organization than meets the eye, as he becomes entangled in a violent shadow war that may have a seismic impact on the New Humanity's future. Republic Under Siege: Threat from Within sees the return of Randal Scott and Stacie Spencer and welcomes newcomer Akane Sugimori, a headstrong Asian female character, to the Wars of the New Humanity series! This emotional, edge-of-your-seat science-fiction technothriller will appeal to fans of N.E. Davenport, David Weber, Django Wexler, and W.C. Bauers, or simply readers looking to have a darn good time!
