The Tales of Faelyn series includes six romantic fantasy books. They take place in the magical realm of Faelyn.

There are four seasonal courts, two celestial courts, and a high court that rules them all.

The Drakenfell Stories are a series of three interconnected romantic fantasy books. They are set in the realm of Drakenfell. The realm is made up of three kingdoms ruled by kings and queens who are the only Fae that have power. The realm is on the brink of war after a prolonged period of peace.
Each book has a complete romantic story, but they do build toward the final book in which war takes over the realm. There are references to the previous books as the next book progresses.
The Elemental Territories are a series of four interconnected romantic fantasy books. They are set in a realm with houses based on the four classic elements of earth, air, fire, and water. The Fae in this realm are ruled by lords and ladies who hold elemental power.
Each book has a complete story with a romance at its heart. The books are related, but they are the least interconnected of the Tri-Realms series. There are references to the other Houses mentioned in prior books.
