The taxi that brings Hazel, Augustus en Frannie to the hotel, holds during the first appearance the license plate number "4V-5RG-K" (which is not a format used in the Netherlands), but seconds later, as the taxi arrives at the hotel, the license plate is shown as "44-STR-2".
It's a twist on a classic saying from shakespeare. The line is about destiny, and how people's fate is not written in the stars, and people choose who they are and what they do:"The fault, dear Brutus, lies not in our stars, but in ourselves if we are underlings." from Julius Caesar.In the book's case, they change it round as they do not get to choose their fate, so it was written in the stars.
