These Wretched Wings: A Savage Seas Universe novel - Savage Seas

For fans of Laini Taylor, Susan Ee, and Stephanie Garber. Angel romance, forbidden romance, bodyguard romance, sunshine and grump, mild to moderate steamy scenes.

Newly graduated from the Training Tower, Idra expects to be assigned to perimeter watch or a city guard position. Instead, she's given the dubious post of bodyguard to Galen, a human inventor indentured to one of the Sky-born lords. Galen is as irritable as he is brilliant, and he's working on a secret project, something that could correct the power imbalance between the Sky-born and the humans.
As Idra spends time with Galen, her sympathy for the oppressed humans deepens, and she uncovers a terrible secret-one that the charismatic Sky-born ruler would kill to protect. Defending Galen from talent poachers and spies is dangerous enough; falling in love with him is forbidden. And helping him overthrow Sky-born supremacy could mean death for them both.
