from fictiondb: Natalie knew she should be grateful to Flynn O'Rourke when he'd taken her beloved Marcus's place and helped her out of a sticky situation. But it was hard to be indebted to a man who strode into your life and took it over. Besides, though Flynn was Marcus's business associate, Natalie felt she couldn't trust him -- Flynn definitely had something else on in mind. She could only hope that it wasn't what was bothering her, it wouldn't do for both of them to feel this overwhelming attraction when they were alone in the hot North African sand!

[Taken from FictionDB:] He was not the man she'd married! The weary and battle-scarred knight returning after seven long years was hailed by his people as Alaric, the new Lord of Penruthin Castle. His child bride, Eloise, had been left a virgin in her marriage bed, and now he saw that she had become a beautiful woman. But the estate, left in his corruptible brother's hands, had been bled dry. Only Alaric, as the eldest legitimate son, had the power to put things right. But Eloise, in her heart of hearts, could not believe that it was her husband who had returned ... for she loved this stranger more than she could ever admit!
