The kind of guy who smiles like he has nothing to prove. From the moment they meet, it’s war. Elliot thrives on pushing buttons. Asher refuses to be provoked.

At her celebration banquet, she went full drama queen: "I owe everything to Kate Mercer. Please, bring her back!" I laughed. Cold. Not happening. Last time around, I was the hotshot detective. But every clue I found? She dropped it first like she read my mind. People started saying I was washed. So I went all in—three months, no sleep, cracked a massive trafficking ring.
