When Erin's charismatic but reckless college ex-boyfriend, Silas, asks her to bail him out of rehab-- again-- she knows she needs to cut him off. Only days after he gets out, Silas turns up dead of an overdose in their hometown of Richmond, Virginia, and Erin's world falls apart. A friend tells her about Ghost, a new drug that allows users to see the dead. Grieving and desperate for closure with Silas, Erin agrees to a pill-popping "séance." But the drug has unfathomable side effects... and once you take it, you can never go back. -- adapted from jacket
