i was just going to mention Torey Hayden !
Ghost Girl
Tiger Child
One Child
Beautiful Child
the Twilight children
all true stories by the author who was a special education teacher working in America. i think she now lives in the uK. these are the the sort of book you dont really want to read, cause the true stories are so horryfying, but on the other hand you just cant them down, even when the tears are streaming down your face
