I have my qualms with some plot holes and the decidedly typical main plot (lowly child with hidden ability is tasked with saving the world), but those go out the window when I take into account how much I enjoyed the last quarter of the book (YAY ACTION SEQUENCES!!). Sanderson's great at world-building and creating interesting magic systems, and that was enough to get me to immediately order the next two books in the series. Hopefully I won't be disappointed...
