The Grave Issue

13-year-old Lexi jimenez had no idea giving her reformed bully a second chance would lead to her best friend's death. She also never thought she'd see her best friend again after the accident. When he appears three weeks later, asking for help, Lexi's positive she's going crazy.

But when she discovers her worst enemy can see him too, she comes to the realization it isn't happening in her head.

Her best friend is a ghost.

She barely has time to register this information before Isaac tells her he isn't the only dead person walking around. The door between the ghost and human world has been thrown open, and they need to close it before the mindless souls destroy their town.
