Code Breakers: Delta (Volume 4)

The fourth and final novel in the Code Breakers series.

Gabriel and Petal have tracked Gabe’s mother back to Hong Kong. But to find her Gabe has to face his old gang and the ghosts he thought he had laid to rest years before. While helping him, Petal stumbles on a way of getting Gerry’s mind out of her head, but like Gabe, she too has to return to a place full of ghosts: Libertas.

Enna is now the Prime Minister of the domed city, and when Petal arrives she discovers Enna has developed her Transcendent technology. However, to give Gerry a new existence, they’ll need more help—help from someone within the Family.

Faced with shifting loyalties and an uncertain future, Petal and Gerry will for the last time face a dire threat to their existence when Jess is kidnapped by a shadowy figure. It’s a race against time to find her and uncover the conspiracy before the Family has the last laugh.
