Lovely Wicked Things (Hollow's Row #3) by Trisha Wolfe

The third and final instalment of the Hollow's Row series.

Halen

I've created a monster. 

When past and present collide, the fallout feels like the death of my morality. Every time I look into Kallum's clashing, feverish eyes, I see a dark omen-the threat of what we'll do to each other if our desires run wild.

While the Hollow's Row case comes to a head, a new heinous player enters the scene. As the Alchemist threatens the town, I'm torn between a promise to help my friend, and my loyalty to Kallum-the man who has sacrificed everything for me.

I've created a monster-but he's my monster. And if I can't control Kallum's chaotic nature, I'll lose him...just as I've lost everyone I've loved.

There could be a future for us, but only if we don't damn ourselves first.

Kallum

The moment Halen St. James crashed my world, I made a vow to harbor her darkness, the lovely spark who ignited my black soul. But now, it's time for Halen to finally step out of her shadows.

I would do-and have done-anything to keep her mine. I've become a villain to protect her. Even from herself.

When she looks into my eyes with recognition, I'm a man reborn, redeemed by her cleansing fire. Only there's a vital piece of our story missing, and without it, I'll always fear losing her-a primal fear that provokes the demon within.

The truth lies somewhere in the murky marsh waters, where killers and philosophers intwine, obscuring ancient wisdoms and feasting on the sweetest nectar.

I was created for her, to devour her heartbreak, and she was designed for me, the muse to the devil himself.
