The two books I have are:
How to Survive (and maybe even love) Nursing School by Kelli S. Dunham
Majoring in Nursing by Janet R. Katz
I also have Trends in Nursing, which is actually a textbook, but I haven't been able to even get through one page of it..
Although they're not instructional, per se, a lot of people recommend Echo Heron's book. You can read about them on her site www.echoheron.com
Other Books on my Wishlist:
Stressed Out about Nursing School: A Student's Guide to Success by Stephanie Thibeault
Mosby's Tour Guide to Nursing School: A Student's Road Survival Guide by Melodie Chavenert
Hope that helps!!
