Three teenagers wrote this book. There is the story of the excellent student who relaxed after eating a drugged biscuit. This led to an addiction which led the good student to being expelled from school, getting heavily intro drugs and landing up in a rehabilitation center where things were equally bad.  The story does have a positive ending as the young man finds the strength to get out of drugs and to go "straight." The second story is about a girl who innocently gets into Satanism.  She almost becomes a human sacrifice but escapes in time and is able to live a normal life. The third story is about a girl who was crippled in an accident. All the stories have a positive ending.
