The Princess with a Storm Wyrm

Across Valeria, Princess Evelyn is scorned as helpless, born without magic and too delicate for a long journey. When her father vanishes and her sister is left crippled, a sky dragon absent for seven years returns to kneel before Evelyn as its sovereign. A court mage hungers for her secret while twenty thousand soldiers close in. Yet Evelyn defeats them without uttering a spell.
