I bought this book to familiarize myself with elliptic curves and their properties. While I have cursory understanding of math topics explored in the book, I am by no measure an expert, so I knew that there will be things in the book that I would not be able to understand without additional studies. However, somewhat surprisingly, I found this book accessible, challenging, and highly rewarding. It forced me to pull together my knowledge of number theory, modular arithmetic complex analysis, and a few other topics, and, as a result, I feel that I have improved my mathematical thinking. I now have other topics I want to explore. I strongly recommend this book to math enthusiasts who are ready to explore elliptic curves.
