Well I don't have a MBA :D, but I do have a masters degree of a similar orientation (Masters in engineering management). I can only recommend the ones I have read and found of value:

[1] Crossing the chasm (Marketing related)

[2] Peopleware (HR related)

[3] How to win friends and influence people (HR related)

[4] The Goal (Business related)

[5] Critical chain (Project management related)

[6] Who moved my cheese (Change management related)

and any of the lean / agile businessy books for ex.

[7] The lean startup

These might not be viewed as traditional MBA material, but my course featured some of these along with more traditional academic books on subjects like financial management, people management, operations etc. I can provide these textbooks to you as well if you like.
