If you want a book about making pasta sauces, this is not for you , but if you want a book detailing how to make different types of pasta, from Lasagna to Tortellini, Gnocchi to Caramelle this book is a MUST buy.
From what I can see this book is very similar to Making Artisan Pasta
by Aliza Green (I think 'Making Artisan Pasta' is the American version of this excellent book.)
Although this is predominately a book about making pasta, there are also recipes for suitable sauce for different types of pasta.
In conclusion this is a great book, one that I would recommend.
