My impression is Gekas is a perfectionist. The recipes when followed exactly are excellent.
This is my "mother"...you can learn to cook interesting meals from the book. If you are single, these recipes "cook on their own". Short prep. time, then you leave them to bake or simmer for ~2 hrs. Gives me time to settle down after work while dinner is "almost ready".
For the price and the quality of the recipes, I have to refrain from the urge to buy another copy! It's a great deal--hands down. Feels like I have wasted my money buying the other cookbooks on my bookshelf.
