Knight and Daye Series

In this new release, Cloud of Dreams, Sherrie DeMorrow explains the backstories of Alexander Pennece DeMilo and Cynthia Lear, before the point of their abduction from Earth.  DeMilo is a 20th century thespian, who is descended from Italian players and the prominent English aristocratic Woodes-Hastings lineage.  Lear is a middle-aged housewife, who suffered a difficult childhood based on a grievous family background and a country which did not understand her.  She relocates to England to marry and in the course of starting a family, she was diagnosed with Asperger's Syndrome. 

It was a quirk of fate that lifeforms from beyond Earth's realm would put Cynthia and Alexander Pennece together, as seen in the previous book, Knight and Daye, by the same author.
