Robin Arianhod is on the run. Trapped behind enemy lines, her only choice is to lose herself in the sprawling capital of Klonn. But hiding in the shadows is a disservice to the rocket pack she escaped with, and to the man she once considered foe. Instead, she’ll enact his plan, harness the incredible power of the pack, and stop the war from the inside.

Wanted posters stalk her every move as rumor fuels the Skylark’s rise, and her attempts at vigilantism attract the attention of more than just the city guards. Robin finds herself embroiled in the machinations of a mysterious underground rebellion—Klonnish citizens as tired of the war as she is.

But are they really her allies, or are they using the Skylark as bait? And can she really trust that her former archnemesis turned his coat? Or will the secret of his true identity lead Robin, and her newfound friends, to their deaths?

Rife with high-flying action, subterfuge, and deception, The Skylark’s Sacrifice is the explosive conclusion to the saga of war-torn Saskwya, and the one pilot who can change it all.
