The Hobbit is a fantasy novel that begins with introducing the readers to Gandalf, who is successful in tricking Bilbo into having a party. This party is intended for Thorin, and his gang of dwarves. This merry group of beings then begins to sing of gaining victory over the famed Lonely Mountain, its treasure, which is currently in the control of a dragon named Smaug. As the music slowly starts to fade, we come to know of a mysterious map, possessed by Gandalf, which can help them gain access into the Lonely Mountain.
Gandalf then suggests that Bilbo be made to carry out this expedition, and after a while Bilbo is persuaded to do so. What follows is their encounter with trolls who seek to devour them. Gandalf is however, successful in saving the dwarves from doom. Bilbo then finds himself separated from the rest of the dwarves. As he fumbles around in that territory, he comes across a ring that seems rather mysterious, and this leads to the occurrence of various other events that keep the readers glued to the end.
