Settle Down Now by Leenna Naidoo

Part Five (final) of the serialised version of the novel.

Ten years on from the events of Unsettled, Charmaine Donnet, now a billionaire, is in the spotlight in the most humilating way. Her search for Mr Right is turning into a media circus, and Robert Hart is not far off in the horizon...
Part Five, the finale, rises to an action-packed climax when more attempted murder and mayhem brings some on board closer together, and reveals the true villains. But there still needs to be a winner in this competition, and it's up to Charmaine to choose her true Prince Charming...

Set in South Africa and the Indian Ocean, with echoes of Rob and Charmaine’s previous life in Scotland, Settle Down Now moves from Durban to Richards Bay to the yacht The Sunflower.
