Behind enemy lines, adversary and ally become impossible to distinguish.
The German invasion of the British Channel Islands shatters Dr. Ivy Picot's peaceful world, forcing her to shoulder the weight of her father's medical practice and hold together a family unraveling under the strain of war. As conditions worsen in Jersey with the arrival of thousands of forced laborers, Ivy's quiet allegiance to the Allies compels her to risk everything by providing medical aid to escaped workers--even as danger closes in.

Dutch engineer and resistance member Gerrit van der Zee volunteers to build fortifications for the Germans so he can secretly send maps and diagrams to the Allies. On his arrival in the Channel Islands, he crosses paths with Ivy, who shows him contempt for the uniform he wears. As tensions mount and their missions grow increasingly dangerous, Ivy and Gerrit must confront the cost of courage, the meaning of sacrifice, and whether love can survive in the shadow of war. Will their covert efforts turn the tide--or will they pay the ultimate price for defiance?

Renowned WWII fiction author Sarah Sundin crafts a compelling historical romance featuring enemies-to-lovers, wartime resistance, and medical intrigue--a tale of loyalty, resilience, and courage when love and duty collide.
