Nevermore by Wrenn Montgomery

Raven Jackson is alone, but not lonely. Thanks to her unique and thriving bookstore, she has endless stories to keep her company.
But one night, after being eyed by a creep at the bar, she reluctantly lets a stranger walk her home. When she falls into bed with him, what started out as a mere safety precaution becomes something neither of them expected.
The morning after, Raven discovers her best friend has been brutally attacked. To make matters more complicated, the detective that shows up to investigate is none other than her last-night lover—Emmett Fisher.
They find a series of clues closely tied to Raven’s past, present, and future. As twists and turns drag them both deeper into the case, binding them together in more ways than one, Raven realizes this is one thing she cannot face alone.
Perhaps, in the midst of it all, the loneliness she’s ignored in her guarded heart for so long will soon be nevermore.
Nevermore.
