Zeus by Marie James

He was my first secret.
The one man I could never seem to leave behind.
As a teenager trapped beneath the expectations of my wealthy adoptive family, I found my escape in Zayne Harmond. He was late nights, hidden touches, and the only place I felt understood. I walked away and joined the Marines, believing whatever existed between us would stay in the past.
I was wrong.
Now I’m a wounded veteran working with Cerberus to take down sex trafficking rings in East Tennessee, and fate has put Zayne back in my path. Only this time, we’re assigned to the same undercover case, infiltrating a dangerous paramilitary organization tied to multiple missing women.
Years ago, getting caught with him would’ve ruined my reputation.
Now, it could get us both killed.
