There Is No Devil (Sinners Duet, #2) by Sophie Lark

Just because he couldn't kill her doesn't mean his enemy won't.

Cole and Mara's relationship has grown to consume them both. Cole, sculptor and killer, finds himself adrift in a depth of feeling he's never known, while Mara, unafraid of his darkness, is blossoming into a successful artist, shaking off the trauma of her youth to finally chase success.

For the first time in both their lives, they might actually be…happy.

But the past has a long shadow.

Alastor Shaw is the Beast of the Bay, a frenzy-killer who once hoped to share his hunting ground with Cole. They never chased the same prey…until the night they both laid eyes on Mara Eldritch. And now, when Shaw realizes the cold-hearted Cole has fallen in love with the girl they once targeted, he plans to destroy him, using Mara as his weapon and pawn.

Cole will do anything to protect Mara, including making her strong enough to protect herself. And soon, he finds himself tempting her deeper and deeper into the depths of violence she never thought she'd commit.

Shaw's hunt won't stop. Neither will Cole's love.

When the time comes for Mara to act, will she be ready to do what needs to be done?
