Forced, before it began

Elizabeth and Darcy are forced to marry each other after a compromise at Netherfield ball. But who orchestrated the compromise? Will Darcy forgive her? What is in store for Elizabeth as the mistress of Pemberley? Will she be able to gain her husband's trust and affection? Major part of the story takes place in Pemberley. The story is WIP and HEA. T for safety. Lot of angst.
