Second the recommendation for Oliver Morton's Mapping Mars.
The Zubrin and Wagner book may still be a good start for the beginner.
Your correspondent might look at the two books of conference papers the Mars Society has compiled and Apogee has published (including a CD-ROM version of the text in a pocket in the back, an Apogee signature). I haven't read them but there is probably some juicy stuff in there for the advanced student of Mars colonization.

(klikkety, klikkety) Ah, here we go: On to Mars and On to Mars 2.
A lot of books are coming out on Martian science in the post-rover period.
