My Jelly Bean

Hayden Locke is your typical teenager who has a lovely family. But being blind is harder than you'd think, especially when there is a killer on the loose. The killer has been killing kids under the age of ten, slaughtering them, making them nearly impossible to identify.
But when Hayden is thrown into an asylum to help get someone out, she discovers the harsh reality of being a toy to other people.
Now, being a proxy of a man named Slenderman, there are obvious reasons why he has them in the first place. One is a very large, seven-mouthed, quick witted, demon named Zalgo.
