This review contains massive spoilers for the original trilogy as well as The Lost Metal . Read with caution! I love Mistborn ; it's one of my favorite Sanderson series. I bought this book as a standalone, but I think it appears in some of Brandon's novella collections as well, maybe Arcaneum Unbound (don't quote me on that). Kelsier died at the hands of the Lord Ruler in a vain attempt to assassinate the god. Or did he? Secret History follows the story of Kelsier after he was stabbed by the Lord Ruler on that fateful day. Too stubborn to die, Kelsier instead lingers, finally convincing the shard of Perserverence that he should instead survive. The Shard binds him to Ruin's power as well, trapping Kelsier in Ruin's prison until the day that Vin released him. Can Kelsier help Vin? Can he become more than a spirit? This book was amazing. I love Kelsier's story so much, and I always thought that Brandon killed him off too early. Turns out he didn't end up dyi...
