When I Arrived at the Castle by Emily Carroll

Like many before her that have never come back, she’s made it to the Countess’ castle determined to snuff out the horror… but she could never be prepared for what hides within its turrets, what unfurls under its fluttering flags. E.M. Carroll has fashioned a rich gothic horror charged with eroticism that doesn’t just make your skin crawl ― it crawls into it.
