The Tigresse and the Raven — Julia Donner

A secret stops Cassandra Seyton from accepting a flood of marriage proposals until Lord Ravenswold sees her. By then, it's too late -- her family hovers on the brink of financial disaster with another social catastrophe about to explode. But neither can resist an attraction that burns stronger than society's dictates and their lack of trust -- his of women -- hers from a fear of discovery.
