Romantic Fantasy Where Both the Romance and the Fantasy Matter

These books make attraction part of the way a fantasy world works: a political marriage, a dangerous magical secret, a shared investigation or a disagreement about who deserves power. Start with Paladin's Grace, Radiance or Half a Soul for a clear central courtship; try Daughter of No Worlds or A River Enchanted when you want the relationship to develop inside a longer story. The range runs from kisses and low-heat affection to explicit adult intimacy. Each recommendation explains the commitment it asks for. Some are fantasy romances with a complete couple's arc; others are fantasy adventures or mythic love stories with different ending expectations, identified where that matters.
