Sarah's eBook is very well written and makes learning pi and just about anything else very easy. Her
use of the graphic arts reinforces the learning process as she steps the reader through a "journey"
of sorts that almost makes you not realize you are "learning" at all. But when you're done with a
chapter, you realize you have memorized a ton of information without any "work". It's a brilliant
work of art and very classy. It's for the scholar or the beginner. Worth every penny for anyone
wanting to add memory routines to their magic or mentalism performances.
