Hemlock by Kiersten Modglin

She thought she’d escaped her poisonous past…

Thirteen years ago, Maggie Ellis left her small town and vowed to never return. In her rearview mirror were two men she loved and an ominous secret that would forever haunt her.
Now, tragedy has brought her back, and she’s determined to forget that fateful night. But in a town like Myers, with familiar faces and chilling memories lurking around every corner, moving on is easier said than done.
Before the ink can dry on the closing documents for her new residence, Maggie begins to feel unsettled. In every room, there’s the unmistakable sensation she’s being watched. The strange sounds, odd smells, and bizarre occurrences only add to her paranoia.
There’s something sinister about her new home…
When she discovers the devastating truth about the house and its grim history, Maggie’s worst fears are realized. In order to survive, she must unearth the secrets she’d always planned to keep buried.

After all, they say that home is where the heart is, but as Maggie knows, home is also where the skeletons lie.
