RoH - Alien Legacy

After decades of ridiculed stories, and evidence only the American government had, aliens landed on Earth. In a spectacular show on New Year's Eve, they rescued the thousand first settlers on Mars as a massive comet slammed into the planet.
As part of the unplanned intervention, the visitors disabled the militaries of all countries. This caused massive economic turmoil as defence industries collapsed and took over half of industrial economic activity with them. Perhaps an even greater dislocation came from the destruction of the myth of the special place of humans in the cosmos held by most religions. Both disruptions drove increasing conflict among humans and the fragmentation of most countries.
The aliens only wanted two things, to gain empathy from humans and to have humans find the cooperation necessary to save life on Earth.
RoH, the half alien human, whose star name translated as 'New dust that spreads new life', had come to Earth as a key part of the effort, but her discovery of a rogue alien hybrid led her into a chase against time. The dangerous mutant threatened both aliens and humans. RoH must either tame him or kill him.
The aliens considered RoH as the first of a new entity that would take the next step for sentient life in the galaxy. She mesmerized aliens and humans as she brought humour and power to all problems.
Less than a year after RoH and her mother Ellie arrive on Earth, everyone including RoH is surprised when she is called to fulfil her role in the galaxy. A star-travelling species emerged from its self-imposed dormancy in the Sagittarian arm of the galaxy when they discovered that RoH existed. This species named the miigis thousands of years before by Anishinaabe of central North America, summon RoH. She leaves Earth amidst hope and heartache to fulfill an unknown destiny.
RoH – Alien Legacy is the direct sequel to the story, Return.
