Runner's Moon Box Set, Books 1-3

Nearly six years ago they landed on Earth--thirty-one aliens, fugitives from a lifetime of slavery and cruelty. Now they were dispersed among the populace, unidentifiable because of their shape-shifting abilities. Includes:RUNNER'S MOON: JEBARAL - Jebaral had hoped for a life. A chance to be free after escaping years of slavery and cruelty. But when he met Hannah Pitt, there was no way he could turn away from her or from the feelings she evoked in him.
But neither could he accept her offer of a future filled with laughter and promise. After all, she was human; he was nothing remotely human. RUNNER'S MOON: TIRON - Tiron had found sanctuary in Crescent City as "Roni." But her own self-hatred, beaten into her at the hands of the Arra, had her earning her living as a common street prostitute. Lieutenant Thom DeGrassi worked vice for the police department.
He had busted prostitutes in the past, but nothing had prepared him for what he felt when he met Roni. RUNNER'S MOON: SIMOLIF - Simolif knew when his brother Jebaral found his life's mate. The blood lines in his arm had increased by one. And the sight of it had thrilled him like nothing else could...unless he, too, could find someone who could accept him for what he was, and who would not scream in fright to see his true self.
He never expected to find Professor Sarah Drumman. As an astronomer, she suspected there were creatures from another galaxy now walking the Earth. More than anything, she wanted to prove her theory to the world.
