good perl textbook for programming beginners

Hi Perl Trainers, each Perl class I teach usually contains one or two
interested folks who have not spent much time learning about
programming.  I want to suggest a textbook (not the Llama Book,
obviously) that can teach them about programming from the ground up
using Perl.  What's the favored book for this purpose?  I had been
suggesting Sams Teach Yourself Perl in 24 hours, which isn't
terrible.

Any suggestions?

thanks

David
