One of the best fantasy books I've ever read. The concept in this one is a fantasy world that is slightly different from our own with the inclusion of allomancers, people born with a special ability to manipulate the world (or themselves) in some way. These include things like being able to push/pull steel, refine your senses or incease your strength. “Mistborns” can use all of these abilities.
The characters and world drew me in with its mysteries and hints at epic problems rotating around our central players. The magical element for this world was the most memorable I can imagine, and I would highly recommend it. You could go with this one on your own, but books 2 & 3 expand on the world.
