This[1] is a fascinating book that delves into this subject in an interesting way. In addition to looking at each letter of the modern Latin alphabet and its history and evolution, the author extrapolates the evolution of each character into three possible future forms that are influenced by different writing implements. It's also quite beautiful in its layout, typography, and presentation of information. Unfortunately it looks like it may now be out of print.
