My Dreadful Darling by H. D. Carlton

“My darling, it is you who is dreadful.”

Reverie Adams has only one goal in life: to keep her head above water with her father’s sinister legacy weighing on her shoulders. But she’s no stranger to drowning—it’s her very first memory, after all, and if her demons have it their way, it will also be her last.
Even with the blood of a serial killer running through her veins, Reverie attempts a normal life at Hollow Canyon University. But there’s a ghost from her past who refuses to set her free, haunting her every waking hour, and he will not rest until he has made her suffer.
Dreadful Sharpe has only one goal in life, but it’s not winning gold medals as an Olympic swimmer. The only thing Dread strives for is vengeance against the family who murdered his mother.
Determined to make Reverie pay, Dread does everything in his power to ensure she never finds a moment’s peace. If he has it his way, she will drown in his wrath until her very last breath.
However, not everything in Reverie’s past is as it seems. Together, they may be forced to face the most harrowing of truths: Dread isn’t the only ghost who intends to make Reverie suffer.
