My suggestion would be: Make your own recipes
Learning to cook is alot of fun, even though it takes alot of time. So just take your time sampling tastes an trying techniques, and then put them in practise with a warning that it might taste odd...
But if I must suggest some cooking book, I would suggest chinese or japanese style cooking. It is very quik and easy and cheap and very healthy. I do alot of chinese style cooking myself, and just leave the rice out and fill myself with the veggies and meat. All yummy.
Still I never follow any exact recipes, just add a bit of this and that where I think themight go well together. Don't be shy, use your imagination and sample.
