The moon rises as the sun sets

Henry Martin, more better known as Henwy online is a successful British YouTuber, living the dream as he makes videos with his best friends Sigils, Nico, and Biffle. One evening he opens his door and is met with something on his doorstep, he is met with a small rag doll. It's a simple doll, covered entirely of white cloth, crossed bright yellow stitches for the eyes and mouth, and another pair forming an x over the heart. Curious, he brings it inside.
That night Henry hears an odd popping sound and looks up to see the stitches breaking over the dolls heart. And in minutes the fabric of Henry Martins reality will be torn apart. Something grim emerges from the pristine white cloth, something that will follow Henry wherever he goes. Something that he can not destroy. It wants henrys life, and he doesn't know why. He has his ally's, his best friends, his strangely intuitive friends, but will they be able to save him from his fate? He has to many questions, no answers, and very little time. As this vicious and demonically clever doll has left this warning on Henry's computer screen:
The deadline is sunset.
The moon rises as the sun sets
Time is running out.
