Vexing complexity

First off, I want to tell you that I’ll be talking and signing at the book festival in Johnstown, Pennsylvania, from April 4th through April 6th. Details are posted here on my website: http://www.gailcarsonlevine.com/appears.html. However, the schedule when you click on it needs to be updated, because I’ll be leaving by about 2:30 on Sunday.
