Why we recommend it

The opener to a shadowy alliance, this one suits readers who love a dangerous man with an agenda and a heroine pulled into his orbit. Expect simmering power plays, possessive intensity, and a world where trust is the rarest commodity. The tone is brooding and controlled, the chemistry coiled tight. Ideal for fans of slow-building obsession and morally grey men who never apologize.
