excellent teach yourself book (particularly for those with no musical experience or piano players)
Starts with very simple exercises and explains how to read music.
I can't afford lessons so it is brilliant for me
Some lovely tunes
Starts by playing tunes rather than chords so someone who comes with guitar experience might not find it so intuitive.
The author has a website where you could get in contact with her
Do be careful with how much you play as I have given myself arm pain after a long practice session probably with poor posture and lots of typing for work
