The Emperor's Soul by Brandon Sanderson

 Shai is in the royal prison after being captured trying to forge the emperor's scepter. As a forger she has the ability to recreate things by using magic to rewrite their histories.  After being condemned to death, she is offered a deal that will give her her freedom if she agrees to replicate the hardest thing in the world, a human soul. As she works on the impossible task, she gains the begrudging respect of one of the imperial elders who may just hold the key to her success and survival.

This book was recommended to me by a young woman I met at a volunteer event.  I haven't read much of Sanderson's YA literature, but what I have read I have liked.  This exemplifies Sanderson's strengths, clever world building and novel magic systems. The main characters are interesting and unusual as well.  Not often does YA literature highlight a relationship between a young woman and and older man. There is no romance, but a very sweet mentor/grandfather thing going on. It says it is a sequel novella to Elantris, (which I have never read) but it works fine as a stand alone. (176 p. 2012)
