About this ebook series

Three billionaire brothers. One sealed estate. And a painting of her dated 1854.

Isla James takes a once-in-a-lifetime job cataloging the Sinclairs’ private collection—an off-limits gallery hidden inside their brutal, beautiful mansion. Lucian’s control is razor-sharp. Damon’s charm is a loaded weapon. Sebastian watches like he already knows how this ends.

Then Isla finds the missing pieces: a forbidden sketch of a woman bound between three men… and a portrait that shouldn’t exist—her face, painted more than a century before she was born.

The house begins to move. Mirrors laugh. Blood appears where there should be oil paint. Every corridor feels like a choice, every touch like a vow. The more Isla digs, the more the Sinclairs tighten their grip—protective, possessive, and dangerously willing to ruin anyone who tries to claim what’s theirs.

But something else is coming for her, too. A Collector who believes Isla belongs to an ancient contract… and a living estate that feeds on repetition, sacrifice, and desire.

To escape, Isla must survive the secrets in the gallery—and the temptation of three ruthless billionaires who don’t share, don’t lose… and won’t let her go.

A dark, spicy reverse-harem billionaire romance with gothic atmosphere, paranormal mystery, and romantic suspense.
