I've been wonderin the same thing. Everything I've seen at my music store of choice is really kinda lame though. Your prabably better off just stickin to the net
I like Ukulele Fretboard Roadmaps, not a song book, but it has bits of songs. It is a very good book for learning chords and scales up the neck I would recommend it to any advanced beginner who plays well in open position but does not know where things are up the neck. Mel Bay has a book Finger Style Solos for Ukulele, great arrangements that are a bit easier then the ones in the John King book, which is also great but I end up comparing my feeble attempts to the late great Mr. King and then I get sad.
The John King classical book is the only one I've bought so far. Coming from a background in classical guitar, I haven't really felt the need to acquire any basic instructional books. I've been able to find everything on chords and stuff online and I've printed out quite a few tabs.
Which reminds me that I should probably order another black ink cartridge before I run out. Hubby would be pretty ticked at me if he needed a map printed out to go on a job and I let the printer run out of ink, since it's attached to my PC.
thanks for your replies i guess the first i will get is the fretboard roadmap, then probably john kings as ive seen that pop up in a few other threads.
