Children Of The Abbey by Regina Maria Roche

Published in 1796, this novel tells the trials and tribulations of Amanda and Oscar FitzAlan, brother and sister who have to navigate the world with no money or status, and hardly any connections. They find love, yet, again and again, things block the way to happiness and, worse, destroy Amanda's reputation. This is the story of abuse of power, loyalty, and, ultimately, love in many forms. - Summary by Stav Nisser.
