The Well of Ascension

This was fantastic. Just finished reading and still absorbing it.

This sequel to The Final Empire (and book number 2 in the Mistborn series) takes place shortly after the events in the first book and takes most of the same characters through the consequences of what happened there, after the death of Kelcier and the Lord Emporer at Vin's hands. It is extremely well plotted and written. The characters are fantastic. There is intrigue, plot twists, surprise, battles and adventure.

...And loss.
