Prey (The Unmasked Series) by Fanny Lee Savage

Four masked men...
Two best friends...
One Night...

“Kitten, we’re always on the hunt.... And you’re our prey.”

Delilah has always played it safe. Not that it was her choice. Her father, a formidable figure, and power hungry business man, always seems to cast a long shadow over her decisions. No matter what she does, Delilah can never seem to escape her father's control.

When Delilah's best friend Cora drags her out of her house to attend a costume party, she doesn't plan on what happens next. Always the responsible one of the duo, Delilah's spent her entire life living up to her father's name and keeping his business under the radar. But when the two are approached by a man dressed in a skull mask and military fatigues, informing her that his friends would like their company for the evening, Delilah has to make a choice.
Play it safe or have some fun.

This is a why-choose MMMFFM dark romance.
