Nebula

Nebula follows Miss Selena during her later academy years in the Akademi Bayangan Tingkat Tinggi, alongside her friends Tazk and Mata. Their shared curiosity pushes them toward a secret quest tied to the Cawan Keabadian and the hidden clan called Nebula.

As the search moves forward, the trio’s bond is tested by ambition, jealousy, romance, and betrayal. The story reveals more of Selena’s past, the rules and dangers of the academy, and the larger history of the parallel world, while new characters and new places are introduced.

The journey also uncovers long-held questions about Raib’s origins and sets up larger conflicts to come. The book ends by opening a new path forward rather than closing the series, with a bonus section that softens the impact of the main ending.
