Deliverance by C.J. Redwine

Secondhand, paperback.

Synopsis: The Electrifying conclusion to the Defiance Trilogy!

Rachel has been kidnapped by enemy forces and is being taken to Rowansmark while Logan is imprisoned in Lankenshire. Separated from each other and their Baalboden comrades, each must find a way to achieve what they desperately want: to ride the world of the Commander and the tech that controls the deadly Cursed One.

Fighting through her pain and embracing the warrior she's become, Rachel will do whatever it takes to escape and find her way back to Logan. But when she learns a secret that changes everything, Rachel realizes that to save the people she loves, she'll have to destroy Rowansmark from the inside out-- if she can survive the journey through the Wasteland.

Logan needs allies if he wants to thwart Rowansmark's power grab and rescue Rachel. But securing allies will mean enlisting the help of the man he hates more than anyone: Commander Chase. Driven by his love for Rachel and his determination to make his word safe, Logan maybe just the weapon the city-states need to defeat the Cursed One.

But as Rowansmark bears down and uneasy alliances are tested, will the pair's love for each other be enough to surmount the unbelievable odds against them?
