Her diamond deal with the CEO / Louise Fuller

"She saved his life. His way of repaying her? A wedding! The offer on the table... comes with his billion-dollar ring! When lifeguard Ondine Wilde rescues Jack Walcott from drowning, she almost regrets it. The billionaire is as rude and entitled as he is gorgeous, so Ondine doesn't expect any thanks. She's certainly not expecting his spontaneous marriage proposal... Jack explains he needs a convenient wife to secure his position as CEO. And while Ondine hates to admit it, she needs financial security for her family. His only rule? No feelings. Which, after a lifetime of heartache, suits Ondine just fine. Until their white-hot chemistry makes a mockery of their on-paper agreement!"--Publisher.
