I have just finished reading Lure of Power and it is an excellent publication:
1. Social combat is great and the action cards for it are also extremely well done, as are the talents as well.
2. Details on the nobility of Ubersreik and the power struggles there. The chance for high level play in the political situation there really excites me.
3. The shame and noble rank are well thought out. However why don't any of the specialist dwarven careers count for noble rank, especially 'thane'?
4. The retainers are also fun, but the moneyman retainer may need a houserule. If you do not limit the amount of money that the moneyman retainer can oversee, the amount of money that can be gained per year through compound interest is horrendous. This particularly applies to Merchant characters who should have around 300GC in money or trade goods to start with. With 200GC a moneyman can turn that into 1400 GC in a year with compound interest, or 660GC if limited to managing only 200GC. I would suggest limiting each moneyman retainer to managing either 100GC or 200GC. If you want to have more of your money managed that way, you have to go out and try and recruit more moneyman retainers.
My only slight negative was that the career ability cards I found to be a little uninspiring. Also The Noble Lord card I think must be missing a prerequisie of at least nobility 1 or 2.
Thoroughly recommend this publication, the best that FFG have done for a while.
