The book provides a good and broad (though somewhat shallow in certain areas) overview of the accountant rules governing IFRS. The case approach is very entertaining, and it covers almost all the adjustment techniques you will need to balance a company's accounts. However, this is not an introductory book to accounting, and so many concepts are taken for granted (eg consolidation methods, risk analysis, etc).
My recommendation is to definitely buy it, read the cases, and keep it in the your office/study desk drawer. It is a great reference book when you come across strange adjustments in the IFRS balance sheets.
