Beyond the death of classmates

wanna know what the story's about? Well my dear companion, you may as well try to read the first chapter. If it caught your interest you might as well read the next chapter right? Should this approach to the written piece not please you, you have the luxury of getting the premise spoiled below this sentence, though I wouldn't recommend it:
School, a secure place to let children spend most of their foreseeable future. However it does happen ever so often that tragedy strikes, this was the case not many years ago. A student attending Ludenberg, a school located not far from the ocean, was found drifting in the lukewarm waters of the sea. Suicide or murder it didn't matter, the death was unexpected, so much so that the remains of the class choose to act as if she was still very much alive.
The deceased student, now believed to be a ghost roaming the school, also came to believe she was still in the land of the living. With each new pack of students attending the class, she too was attending it with them, unknowing of her own situation. It became clear that something was amiss in that class and those attending it. Death became a given, it laid its thick curtain of smoke and gas around each of the students, letting them inhale the poison. So it began, the death of the class. Each month another would succumb to the sweetness of the grave.
O' what may happen as they fall cold and limb?
