I just finished reading all of the so far published Secret Projects by Brandon Sanderson, those boing Sunlit Man, Yumi and the Nightmare Painter, as well as A Frugal Wizards Guide to Surviving Medieval England.
I am curious to see how others liked them as well as rated them. In my opinion SLM is the best (pretty much being a SLA standalone), with Yumi following and, Frugal coming in last but still being better than most books that are published today.
