Her Wicked Viscount - Ladies in Scandal

When her father mysteriously goes missing, Miss Ava Hamilton's sheltered life is turned upside-down. Tossed onto the streets by her malicious half-brother Ashton, Ava must fend for herself and the two orphans in her care. Knowing her father would never abandon her, Ava vows to find him, and as her quest begins, she stumbles upon an unconscious Lord in need of saving. The Viscount returns the favor and joins her search, but resisting their attraction is entirely another matter.
Lord Daniel Steel, Viscount of Hedgerow Manor, is used to doing as he pleases. Charming and wickedly handsome, he bristles against the idea of marriage when his father threatens to cut him off at the end of the Season. But delicate debutants aren't for him. Preferring financial independence, he seeks an investor for a business deal. Except, the gentleman goes missing, and suddenly he's at the mercy of a determined and tempting young lady too delicate for the streets of London.
Now Daniel must search for his vanished investor before time runs out, and he finds himself reluctantly betrothed.
