This classic novel of love and war set amidst the devastation of World War II and its aftermath follows sister-and-brother twins who meet shockingly different fates, but whose bond will last forever. Cambridge, 1942: Twins Tessa and Theo are each eager to do their part in the war. Theo is recruited by the Royal Air Force (RAF) and disappears into the skies, while Tessa jumps at the chance to join the Special Operations Executive (the SOE), devoted to spying and sabotage in German-occupied France. It will be dangerous, highly classified work, but Tessa is no stranger to secret-keeping. Two years later, Theo comes home. Tessa does not. Theo, a clandestinely gay man at a time when homosexuality was illegal, is physically wounded and emotionally broken by the deaths of his fellows and the disappearance of his sister. He is angry and cannot stop pursuing answers about Tessa’s fate, even though he will pay a steep price for his quest. Years later, PhD candidate Edie is deep into her research on the SOE when its lead her to Theo. The old man and young scholar form an unlikely partnership and together, they finally uncover the truth about Theo’s beloved sister—a truth that stretches all the way back to the summer Tessa spent in France before the war had even begun. Both intimate and sweeping, elegantly written and unflinchingly honest, The Shock of the Light is a novel of bravery, the brutal cost of war, a sibling bond that outlasts even death, and the redemptive love that grows in unexpected places.
