Dragons of the Dwarven Depths (Dragonlance: The Lost Chronicles, Vol. 1)

the long version

In an untold story from the War of the Lance, the companions have saved the refugees of Pax Tharkas and led them to a hidden valley. For a time, they are safe, but the forces of the Dragon Army are in pursuit. As Tanis and Flint seek out a haven in the dwarven kingdom of Thorbardin, the rest of the companions face their own challenges. Raistlin is strangely drawn to the haunted fortress known as Skullcap. Sturm seeks the legendary Hammer of Kharas, the forging tool of the fabled dragonlances, while Tika Waylan must make a perilous journey to rescue those she loves from certain death. It is the dwarf, Flint Fireforge, who faces the most crucial test. As the heroes race against time to save the lives of those dependent on them, Flint is forced to make a difficult choice, one on which the future of mankind may rest.
