Above and Beyond

In the Andrew Michaels trilogy our reluctant billionaire goes from hospital bed to a Spanish Dynasty, and in this, the final book, Andrew has yet more assassination attempts made against him, landing him aboard a nuclear powered Aircraft Carrier. He is then 'tricked' into becoming a 'reluctant' diplomat (with benefits), ending up with him being held hostage in the desert, whilst the world tries to sort itself out. He finally meets the second love of his life, but nothing is ever simple for Andrew, she is a 'married' widow, who still happens to be a virgin, but not to be put off he travels around the world tracking down the reluctant corpses, ending up in the Maldives where Charlie - who was 'killed off' in the second novel, makes a 'ghost' appearance and fulfills a 'burning' ambition. Does he live 'happily ever after'? - I hope you enjoy finding out. P.S. who is 'Charlotte the Harlot'?
