Ada text for CS2 course

[bonak@herky.cs.uiowa.edu (Esmail Bonakdarian)]

I am looking at a possible replacement for our current Ada text in use 
for the CS2 class I teach. I currently have been using the 3rd edition 
of "Programming in Ada"  by Barnes, but now am looking for alternatives.
One book that I am considering is "An Introduction to Ada" 2nd edition
by S.J. Young. Anybody use that book as a text?

The Ada course I teach has a prerequisite of one semester of programming
(this is Pascal at this time). Many of my students complain that the 
Barnes book is poorly organized, too wordy and overwhelming with 
details. While I do not agree with all of their complaints I can see
their point of view and I am willing to look at other books.

Any recommendations?

Thanks,
Esmail
