Tycoon's One-Night Revenge

She was engaged to Alex Carlisle from book#3 Of Princes of the outback - Bronwyn Jameson

Amnesia had stolen 30 year old millionaire businessman Donovan Keane's memory. But one look at 28 year old treacherous beauty Susannah Horton, and Van could picture every delicious detail of the weekend they'd spent in his bed. She'd staged their affair to ruin an important deal--a deal about to go to her fiance. Not that Van would let that happen. During one hot night, he'd destroy her engagement, take back the deal and walk away with all the memories he'd need. Good thing, because he'd never be able to get her out of his mind.
