Hi, I've been thinking how much I'd like to read a book where the characters have to travel between different countries to do something adventurous. E.g. solve a mystery, kill a vampire, do a heist, discover an ancient tomb… doesn't matter what exactly, but the stakes need to be high. It's not neccesary, but I also really like it when they travel via private jets and have tons of money to burn to accomplish their goal. Da Vinci Code comes to mind, or The Fifth House of The Heart.
