Succubi keep falling through dimensions into my Chicago apartment. I became an incubus to survive them. Four gorgeous demon women share my bed, my bond, and my supernatural energy. And I just walked through a portal into their world.

If you haven’t met Lyra, Cherry, Raven, and Morgana yet, start with Book 1: There Is a Succubus in My Room. You’ll want the full experience before the demon realm hits you.

The last incubus walked these streets four hundred years ago. Every succubus in the Eighth Circle can smell me from across the marketplace.

My addictive essence radiates through entire districts here. Succubi stop mid-stride, tails rigid, eyes blown wide. I can’t buy bread without causing a scene. The bread is also alive. That’s a separate problem.

The sky is purple. The buildings breathe. Complimenting someone’s horns is apparently a marriage proposal. I found this out within five minutes of arriving.

Lyra’s wings work here. She lifted off the ground laughing, and the joy through our Soulbound bond nearly knocked me flat. She’s more powerful in this realm, more vivid, and what she whispers to me in the Spire Gardens changes everything between us.

Cherry found the Nectar Quarter and declared it paradise. A whole district where nobody cares how loud she gets, where her exhibitionism is normal, and where her massive tits and demon-realm-amplified illusions cause a district-wide energy spike. She has zero intention of ever coming home.

Raven’s shadows curl around her like old friends in this dimension’s deeper darkness. But the streets she grew up on hold more than nostalgia. Her mentor is three streets east. Still breathing. Still not forgiven.

Morgana came for the Forbidden Archives. Two centuries ago, they expelled her. Now she needs what only they contain, and the living library opened its doors for me without permission. The head archivist’s spectacles nearly hit the floor.

The demon realm hasn’t seen an incubus in four hundred years. That means four centuries without what only an incubus can give them.

A pleasure house hostess whose nectar is served warm, straight from the source. A warrior succubus who’s dominated every partner for two hundred years and fully expects me to kneel. A shy archivist who takes off her glasses for the very first time.

None of them are ready for what happens next.

Meanwhile on Earth, my sister showed up at the apartment, found a golden retriever, an interdimensional bureaucrat, and zero explanations. The bureaucrat tried lying. It went poorly.

And somewhere beneath the Crimson Court, behind dimensional glass, a prisoner with glowing seals opens her eyes for the first time in decades and whispers: “You came. I’ve been calling.”

The Constellation is growing. The pattern is bigger than anyone understood. And someone erased the answers before we could find them.

  • The first incubus in four centuries loose in a dimension built for pleasure
  • Four bonded succubi at demon-realm-amplified power, plus encounters that redefine hospitality
