Dragon Trials (Return of the Darkening #1) by Ava Richardson (epub) [BluA]

Summary:
High-born Agathea Flamma intends to bring honor to her family by following in her brothers’ footsteps and taking her rightful place as a Dragon Rider. With her only other option being marriage, Thea will not accept failure. She’s not thrilled at her awkward, scruffy partner, Seb, but their dragon has chosen, and now the unlikely duo must learn to work as a team.

Seventeen-year-old Sebastian has long been ashamed of his drunken father and poor upbringing, but then he’s chosen to train as a Dragon Rider at the prestigious academy. Thrust into a world where he doesn’t fit in, Seb finds a connection with his dragon that is even more powerful than he imagined. Soon, he’s doing all he can to succeed and not embarrass his new partner, Thea.

When Seb hears rumors that an old danger is reemerging, he and Thea begin to investigate. Armed only with their determination and the dragon they both ride, Thea and Seb may be the only defense against the Darkening that threatens to sweep the land. Together, they will have to learn to work together to save their kingdom…or die trying.
