My Lord Kasseem (Harlequin Romance, No. 2534)

They were from two different worlds. From the moment she saw him, Alex was filled with tempestuous longing for the enigmatic Sheik Kasseem ben Omair. But she was an ordinary librarian and he an imperious son of the desert who’d vowed never to marry outside his own people. Compelled by his mastery and the depth of her passion, Alex found herself impossibly bound to him. Though she might never be his wife, he would always hold her heart captive.
