101 Curses is an incredible collection of the nastiest spells around. Arguably, it's one of the most evil and sinister books on the subject. Whether you're just curious, or you're on the market for curses, this little gem aims to satisfy both your curiosity and your problems.
This book is exactly what it says it is, and I'm not messing with it. <3
I am inspired to write my own book of 101 modern-day curses, though -- "may your printer jam when you're stealing others' ideas" or "may your cable cord get cut if you listen to F*x news"- you know, things like that.
