Bought a blues book once with a cover-CD. Turns out that all of it was just variations on I-IV-V. Bsides, books of '100 greatest licks' are a waste of space - since when was a flashy lick (if you'll pardon the expression ;-) more important than a good song? The main attraction with them is getting the jam track CD, so you don't have to keep the bass-line going as well (the biggest problem for solo blues stuff).

Blues CDs are dirt cheap at Woolworths and places like that - you can pick up John Lee Hooker stuff and the like for next to nothing. If your young person has a reasonable grasp of chords, they'll probably get more enjoyment out of listening to it and messing about over the top. JLH is good for that cos he doesn't do lots of fast stuff and his music is pretty spare (not prone to filling every available space with notes!), which makes it easy to jam to.

Grab.
