Asgara,
Quetzal mentions Futuymas "Science on Trial". I can't recommend this more, it took me abut a year to get a hold of a copy since it went out of print. Happily this is no longer the case & you should be able to obtain a copy through Amazon (granted, I live in the UK).
If you think you're at the undersgrad level, then look no further than Futuyma, once again; "Evolutionary Biology" 3rd Ed. By Douglas J Futuyma.
Another excellent creation refuting whopper is "Science & Earth History", by Arthur N Strahler. This is a large format hardback, 500 pages, & sets out to refute all creationist arguments. It is readable by the layman, & introduces the science before making it's arguments. Perhaps this would be a good buy for your friend? I still refer to it now.
Regarding your friend, as long as she came here to genuinely find things out, & used an "I'm ignorant of science, but I have some questions regarding evolution, the flood etc", she'd be fine. It's only creationists who come here spouting their misinformed nonsense that get slammed, & even then only after refusing to address the relevant raised issues.
