Forbidden Lessons (en Inglés) - Gabriel Steele

When Caleb Wren arrives at his father's door, he brings nothing but a duffel bag and a grief too heavy to name. Twenty years old and newly untethered, he is looking for somewhere to land - not for someone to fall for.

But the house on Meridian Street holds a surprise: Sera, his father's girlfriend, whose quiet intelligence and uncanny warmth draw Caleb in before he has the sense to resist. What begins as stolen glances and careful conversations slowly becomes something neither of them can walk away from.

And then Sera tells him the truth about what she is.

She is not human. She never was.

In a world where humanoids walk among us and love refuses to follow the rules anyone has written for it, Caleb must decide what he believes about connection, about loyalty, and about the kind of courage it takes to want something that the world has not yet learned to name.

Forbidden Lessons is a passionate, slow-burn romance set against a near-future cityscape - a story about grief, desire, and the devastating simplicity of being truly known by another.
