In a war for the skies, trust is the sharpest weapon.

When Dervy Kettel joined Fifth Flight, she swore she'd prove herself-fast, fearless, and ready for any mission.

But when her new squad's latest task sends them deep into ogre lands, she's paired with the one rider guaranteed to test her patience: Chakston Ward.

He's new, he's infuriatingly confident, and he's hiding something. His dragon bears an ogre slave-bond-an omen that could doom them all if detected.

Together, they'll face enemy skies, daring spells, and the kind of sparks no storm can drown.

But when trust falters and danger closes in, will thunder strike between their dragons...or their hearts?

Read this fourth installment of the Fifth Flight romantasy series because when sparks fly, hearts burn.
