just get past the geometry,
This review is from: An Imaginary Tale: The Story of "i" [the square root of minus one] (Paperback)
I imagine that quite a few people who try to read this will be put off by the first section of geometry (unless you're one of the two people into geometry). It is a bit tortuous but persevere and you will be rewarded. After this point the book really becomes excellent.
Be aware though that this book is essentially a collection of derivations following the history of the use of i and complex numbers. As such it is very equation heavy, so if you want a popular science type book that talks about the ideas but not the nitty gritty (a la The Music of the Primes: Why an Unsolved Problem in Mathematics Matters) then look elsewhere. However, if you don't mind the equations and are prepared to put in a little mental effort then you will find many amazing results.
