Bartered Proposal (The Billionaire's Wife #1)
Ava Lore

Or was. When he shows up on her doorstep and tells her he blew the GDP of Africa on bad investments and failed businesses, Felicia knows he's getting what he deserves. Except that's not all: her mother is sick, and he can't afford the payments for her treatments. He has a backer to save his company, but there's one catch: Felicia must marry him!
A modern woman, Felicia balks at the implication that her hand can be bought, and she sets out to give this backer a piece of her mind. But there's more to Anton Waters than money and power, and when they come face to face, Felicia realizes that saying no to his proposal may be harder than she thought!
