SWAGG: The Creatorverse
Origin Stories. Crossover Chaos. One Last Chance to Save Him.
They’ve battled secret covens, vampire dynasties, Egyptian monsters and dark-spy agencies. But nothing prepared them for each other.
In this crossover saga that collides four origin stories into one explosive mission, a team of brilliant, broken teens is recruited by the shadowy Gideon Flynn. Their task? To use their elemental powers as Spy, Witch, Alchemist and God - to redeem him and save the world.
And - maybe - themselves.
The SWAGG Creatorverse
What started as four separate series - Jane Blonde, Matilda Peppercorn, Jack BC, and Stein & Frank - was always building to this. SWAGG isn’t just a team. It’s a universe.
With 19 interconnected books, fandom Easter Eggs, recurring characters and overlapping lore, this is a creatorverse for fans of layered storytelling.
Each SWAGG book is told from one team member’s POV:
-
Spook — Jane Blonde
-
School of ICE — Jack BC
-
Sorcery — Matilda
-
Soulforce — Stein
At its heart is Gideon Flynn - a young man with secrets of his own. And a chance for redemption that may come too late.
