Traitor’s Code by Jane Killick

When a dying fugitive entrusts Cassy with a forbidden code, she must protect a secret which promises to save humanity – and threatens to get her killed.
Freelance spaceship captain “Cassy” Cassandra investigates the mysteries of a code stolen from Prince Stephen’s family. He pursues her as she evades soldiers, fights pirates and calls in favours to return to her home planet of Fertilla.
There, forced to confront her long-buried past and its connection to a dead king, she realises all her answers lie with Prince Stephen. As they develop a relationship, Cassy cracks the code behind his back and knows she must betray him to bring salvation to the galaxy.
A page-turning space adventure, Traitor’s Code mixes murder and intrigue with the heartache of impossible love in the first, unmissable instalment of the Freelancer trilogy.
