I used Uncle Rod's Ukulele Boot Camp. Don't buy books until you understand which book you need and why you need it. Lessons here on UU, HawaiiMusicSupply, and on YouTube.......lots of tutorials on "everything" uke. Just enter Ukulele how to and fill in the blank. Trying to learn by just playing songs is too hard for most............trying to learn how to hold, strum, fret, unfamiliar chords and lyrics all at the same time is too much unless you're some kind of prodigy. New song, master the chords first, the strumming/picking pattern, then learn the lyrics, then combine them. Good luck.
