The main aim of the book is to give an account of Hidas results on arithmetic invariants in an accessible way. The book is intended for mathematicians with some background on modular forms and is worthwhile for both graduate students and experts. There are numerous examples, exercises, and remarks, all aimed at carefully helping the reader. In conclusion, this book is a very welcome addition to the mathematical literature.
