The Harvesting (The Harvesting #1)

An alternate cover edition can be found here and here.

It's all fun and games until someone ends up undead.

Though Layla reluctantly returns home to rural Hamletville after a desperate call from her psychic grandmother, she could never have anticipated the horror of what Grandma Petrovich has foreseen. The residents of Hamletville will need Layla's help if they are to survive the undead apocalypse that's upon them. But that is not the only problem. With mankind silenced, it soon becomes apparent that we were never alone. As the beings living on the fringe seek to reclaim power, Layla must find a way to protect the ones she loves or all humanity may be lost.
