The Final Empire
Review written by Hector Chan
Vin is left behind by her brother, Reen.  She is travelling with bandits but she always long for more.  She is raided by a group led by Kelsier.  He has other plans to assassinate the Lord Ruler of Luthadel, whose wife turned on him and was killed.  Others are not so sure, but go along with their leader anyway.  Kelsier is a mistborn, fluent in all metal, and Vin is too but she doesn’t see it at first.  Vin has a double duty to spy on the many houses through attending balls as Lord Renoux’s daughter.
I highly recommend it and am reading the second book in the trilogy.  Brandon Sanderson really delivers good fictional characters that are believe and have flaws.
