Scalebound - Logan Piercey

FOURTH WING by Rebecca Yarros meets POWERLESS by Lauren Roberts and LIGHTLARK by Alex Aster in this fairytale story of dragons, plagues, and curses.
Aurelia grew up knowing she was the result of the tattoo on her father's wrist. The engraved sign came from killing a dragon, which caused him to obtain one of the five curses. Aurelia was that curse. She was a Scaleborne, half-dragon and half-mortal, and had been hidden in a tower her entire life, as she was wanted for her golden blood.
When diseased creatures spread plague and famine across the lands, she is the only one who can save her kingdom. She is quested to search for the golden dragon relic, that grants only one wish and can only be seen by the Scalekind. Being the only person who can see the egg, she goes on a journey to save her kingdom from the diseased creatures and the extinction of dragons, all while being hunted for her golden blood.
With dragons possessing elemental abilities and being able to transfer these gifts to their riders, Aurelia has to claim her ability with her connected dragon and train before the kingdom is immersed with plague by the deathlies or she is killed for her gilded blood.
