Refresher books?

Hello,

I am looking to see if there are any good "refresher" RN books out there? I have been a nurse for 4 years now. I did a year in a nursing home, 1.5 years in a family practice clinic, and I did about 9 months in utilization review and have been in Employee Health since.

I know I don't have the best of experience in jobs but my first year as a nurse in the nursing home I thought I made a mistake by going into nursing and was constantly trying to find my passion/niche in nursing. I never was able to get into a hospital, never even got an interview, so I got really down and basically gave up on the hospital dream. I don't think I had the best clinical experiences in school either, adding to my anxiety.

Any who, I like my job now, and I am going back for my MSN with an emphasis in Public Health. I still sometimes feel like nursing wasn't the right path for me, but I can't just pack up and do something completely different and thought I would expand on the education I already have.

I was just wondering if there are any good books for refreshers for RNs? Any suggestions?
