Night of Madness by Lawrence Watt-Evans

This book is about a group of people who suddenly had magical powers bestowed upon them in the middle of the night. The powers came as a big shock to all. Many people disappeared and the other people ceated chaos in the streets. The people with the new magic, called warlocks, were considered evil and dangerous by everyone else. The warlocks have to control their new powers and convince everyone else they are trustworthy before they are all exiled or put to death. This was an excellent book that depicted really well how people think and treat others and how they react when faced with something dark and unfamiliar.
