The Billionaire's Secret by Nana Malone

5.0

Such a great conclusion! This story has everything, surprise sibling, mystery, danger, espionage, intrigue, and a piping hot couple (Zia and Theo) on an unforgettable adventure to see it through. I love this author's style, there is a whole series of books now with the main characters prominent in other stories as well. You don't have to read about the other couples to understand this one, but you do need to read the first book of this duet. I promise you though after reading Theo and Zia's story you will want to know the rest of the royal family and the security team. A great couple and a hot fun story to get caught up in!
