Irony is a literary device that you can identify when there is a discrepancy between what is said and what is meant, or when the outcome of a story, or statement, is opposite to what you expected; this outcome tends to be tragic or humorous, and it tends to catch our attention, makes the story memorable and helps us think about the theme (the central message) of the literary work.
This is the literary device being used in the passage provided: Veronica did her best to stay healthy during her vacation, however, despite her effort, she got sick the next day she arrived to the hotel! The outcome of this story turned out to be a funny one and just the opposite to what was expected.
