No Way to Treat a Lady — Jane Atkin

She'd married another man to escape an obsessive love. But Leanne Ryan was divorced now and vulnerable. And Joe Dano, ex-hockey star, had become a tycoon, driven by his need to possess this ice princess who'd gotten away. Now Joe had the upper hand. The war of wills began with a one-year "marriage of convenience": his financial backing for her troubled company in exchange for her total surrender. She hated him; she loved him.
Again and again passion drove her back into his arms. But how could she turn one embattled year into a lifetime of love?
