The Nightsilver Promise (Celestial Mechanism Cycle #1) - Annaliese Avery - Bog

"In the empire of Albion, the Great Dragons of old are long gone--hunted for centuries by cruel emperors fearing the power they possessed. Now governed by the science of Celestial Physicists, everyone's life is foretold by the track of stars on their wrist. When Paisley Fitzwilliam receives her track, she discovers that she is destined to die before the end of her fourteenth turning. Then, when her mother goes missing, Paisley is the only one left who can protect her Dragon Touched brother, Dax, from being exposed as a descendant of the Great Dragons and taken by the Emperor's men. But an ancient power stalks the sewers of London--the Dark Dragon is rising, intent on restoring the Great Dragons of old at any cost, even if that means tearing Paisley's family apart."--
