Both secrets and recall are good books to have around. For your 3rd year rotations, I believe the Blueprints in OB, 2nd edition is best. If you're just wanting something to keep with you, I would get the secrets, it is easier to study from than the recall in my opinion. A good pocket reference is the little red book, "obstetrics, gynecology and infertility" by Gordon, but unless you're going into OB, i wouldn't really bother with it.
