Jonah is a short book of the Bible. You'll find Jonah the 8th book from the end of your Old Testament, #5 of the 12 minor prophets. The main question you will encounter about this book is whether it is history or not. About 150 years ago in the first heyday of Protestant liberalism, so-called "scholars" began saying that Jonah was not to be taken as history. The main obstacle to believing the book is actual history is the miracles, especially Jonah being kept alive 3 days inside the big fish. But rejecting the historicity of the book of Jonah is the fruit of unbelief. It's silly to say you believe in God but you don't believe the miracles in the Bible. The book is written in narrative style with nothing to indicate it is anything other than history. Jonah himself is a known historical prophet. If you don't believe this book is history, you don't believe Jesus. Matthew 12:38 –41 (LSB): Then some of the scribes and Pharisees answered and said to Him, "Teacher, we want to see a sign from You." But He answered and said to them, "An evil and adulterous generation eagerly seeks for a sign; and yet no sign will be given to it but the sign of Jonah the prophet; for just as JONAH WAS THREE DAYS AND THREE NIGHTS IN THE BELLY OF THE SEA MONSTER, so will the Son of Man be three days and three nights in the heart of the earth. "The men of Nineveh will stand up with this generation at the judgment, and will condemn it because they repented at the preaching of Jonah; and behold, something greater than Jonah is here. 1 - Who, What, When, Where, Why?
