Hear No Evil - Sara M Garringer - Bog

Death seems to follow Simon wherever he goes, beginning with his parents' accident, his uncle's heart attack, and his aunt's suicide, earning him the unfortunate nickname of "The Grim Reaper". So when the most popular girl in school disappears the same day he gives her a ride home then turns up dead a few days later, he's everyone's prime suspect.
But Simon does have something to hide: he can see ghosts and on a few horrifying occasions, can even become possessed by them. So when the spirit of the dead girl appears before him begging him to help save her little sister from suffering the same fate as her, Simon finds himself being tested like never before. Does he have the strength to overcome his fears in order to save an innocent life?
