Unraptured

Kellianne hasn't fallen prey to the Rapture virus--yet. But it's taken hold of her stepmother, threatening Kellianne and the other survivors in her neighborhood. Now her uncle is missing too, and Kellianne feels like she's the last person others should be asking for help. But in this a post-apocalyptic future, no-one survives long on their own, so Kellianne must keep everyone safe while coming to terms with her stepmother's last request--a quick end.
