Heartless Sky

Tory and Darcy Vega are twin heirs to the throne of Solaria, and the man who holds it, Lionel Acrux, took it by usurping them. The sisters are in hiding with the Royalist Rebels in a secret base. There they train to master their Phoenix powers and plan to remove him from power.

The Heirs stand with the twins, and the bonds that once tied several of them to Lionel are now broken. That frees them, but it does not make them safe. A deadly curse hangs over the group, and a traitor is a threat from inside the rebel camp.

This is romantasy, the seventh book in the Zodiac Academy series, and it picks up directly after Fated Throne. Restless Stars follows it. The rebels gear up for open war, and the story drives toward a last, bloody battle for the crown, with the romances at the centre of the cast on the line as well.

It reads as a long, spicy, high-drama instalment. It leans on everything the earlier books have built, so it suits readers already deep in the series and is not a place to start.
