Untamed Italian, blackmailed innocent

"No woman has ever shunned wicked Italian tycoon Zac Delucca! But sweet, studious Sally is in a world of her own, looking after her sick mother -- little does she realise her unfocused lack of interest is driving Zac's fury! Especially as her father is responsible for embezzling millions from his company. There's a debt to be paid. Zac will offer Sally an ultimatum -- become his mistress on demand, or risk ruin! He's confident she'll make the right choice."--Publisher description.
