An entire book about dots? Absolutely!
Most Syriac grammars include a few pages about Syriac dots in their various forms. However, such brief introductions can still leave you feeling confused.
Kiraz does so much more than list the meanings of different kind of dots. He explores the history, the rationale, and provides lots of examples for each kind of dot. By the time you get to the end of the book, not only will you have been entertained, but you will feel much more confident about reading any Syriac text - regardless of how many dots are used therein!
