The crew of the skyship Phoenix have come a long way since Dorian Valmont and his accidentally-bonded dragon Solaris joined them almost a year ago. But the Phoenix is gone now, and Emperor Callahan continues to consolidate power. Their last hope to defeat him lies with the mysterious and secretive Order of the Silver Dragon. With the Order, Dorian and Solaris can finally learn what it means to be dragonauts. But when Dorian is tasked with guarding a prisoner, he discovers that the Order's secrets may well spell their downfall. Tai thought she'd found a home with the crew of the Phoenix, but with the ship destroyed, she is once again adrift and out of place. When a dangerous man from her past offers a risky opportunity, she seizes the chance to prove her worth. Tai soon finds herself on the run with a stolen dragon-and a secret that could shake the world of Cyrna to its core. Time is running out. While Dorian and Tai struggle with conflicted loyalties, the emperor comes ever closer to sinking the floating lands. The pair may yet restore the world's magic, right an ancient wrong, and thwart the emperor once and for all, but to pull it off, they'll need to figure out who they can trust, and where they truly belong.
