Archangel Book one of the Chronicles of Ubastis

"Earth is dying, and we have begun the search for a new home. Our hopes are pinned on Ubastis, an untamed paradise at the edge of colonized space. But such an influx of people threatens the planet's unstudied ecosystem-before these settlers arrive, a tenuous research colony must complete its essential and desperate analysis, lest humanity abandon one planet only to die on another. The Ubasti colonists barely get by on their own. To acquire the tools and supplies they truly need, the colonists are relegated to selling whatever they can to outside investors. For xenobiologist Vashti Loren, this means bringing Offworlders on safari to hunt the specimens she and her fellow biologists so desperately need to study. Haunted by the violent death of her husband, the heroic and celebrated Lasse Undset, Vashti must balance the needs of Ubastis against the swelling crush of would-be settlers. As she negotiates her grief, Vashti struggles in her role as one of the few colonists licensed to carry deadly weapons, just as she struggles with her history of using them. And when she discovers a genetically engineered soldier smuggled onto the surface, Vashti must face the nightmare of her husband's murder all over again. Vashti must protect herself, her daughter, and all of Ubastis as she is forced to draw alliances with old enemies, re-evaluate old friends, and take planet-wide action against those who threaten her world. Vashti stands at the threshold of humanity's greatest hope, and she alone understands the darkness of guarding paradise" --
