I should probably add that a lot of the introductory work can be done without a book. Simple tunes (e.g. Frere Jacques) in D major, firstly in the lower octave and then in third position. Practicing the shift by itself, singing the interval to anticipate the target note, and also comparing the sixth and the octave against the adjacent open string. Jumping up to a fourth-finger harmonic can be another useful exercise for those reluctant to leave familiar territory.
I agree with this - there is a fair amount of introductory work for which no book is needed. When I do progress on from there, it's not one specific book, but tunes taken from a variety, which I loan out. Being in Scotland, one which I do use quite a lot is
The Scottish Folk Fiddle Third Position Book, because most kids here know a variety of traditional tunes. Another good one is
Shifting: Thirty Studies for Young Violinists, but this also includes 2nd, 4th and 5th, so a bit more advanced.
