Best Business school books, essay prep, resources?

Hey everybody - I am on the last leg of my consulting stint before bouncing to a new job with the hope of applying to business school within the next 1-2 years. Luckily, my current consulting job does give budget for business school prep materials and I have not used any of it (~$1K). Before I leave, I was hoping to purchase some business school self-help books that would be helpful for when I apply!

I have already taken the GMAT so GMAT prep books are out. I have looked on GMAT club and WSO but seems to be some mixed reviews as the best books and would love to get the "Top 10" books from fellow monkeys.
