Skullduggery Pleasant is an intriguing book series, and personally one of my favorites. You can discuss it here.

I personally think it's a very slight Harry Potter ripoff, but otherwise it's very well written. The only drawback is the unrealisticness of it. I've figured out that if Valkrie and Skullduggery just spammed fireballs and pushing enemies back with Wind blasts, they could pwn most of the creatures easily. The only problem was, those creatures cleaned out their clock, because they didn't spam their powers.

Of course, if they did, there would only be around 3 books instead of 5, because the Grotesquery, Serpine, Vengous, White Cleaver and Diablerie would all have been defeated in about 3 pages, instead of 300. (No, I'm not exaggerating, the Grotesquery took over 300 pages to hunt down, then about 35 pages to kill)
