The Raventree Society. S2E1: Grace Cemetery - The Raventree Society, #6

As Kyle returns home to bury his brother Tyler, and heal from vicious supernatural attacks, he's expecting an uncomfortable reception from his family. What he isn't expecting is that the horrors he's been experiencing have followed him. Kyle's sister is clear about her desire to reach out to Tyler's spirit, but when she disappears in the middle of the night, she might find more reason to fear than to hope.
And Kyle is left to decide if it's better to go after her, or if she's safer far away from him. He is beginning to wonder if the danger will go wherever he does.
