WINNER OF THE CARNEGIE MEDAL


Romania, 1989. Communist regimes are crumbling across Europe. Seventeen-year-old Cristian Florescu dreams of becoming a writer, but Romanians aren’t free to dream; they are bound by rules and force.

Amidst the tyrannical dictatorship of Nicolae Ceaușescu in a country governed by isolation and fear, Cristian is blackmailed by the secret police to become an informer. He’s left with only two choices: either betray everyone and everything he loves, or use his position to creatively undermine the most notoriously evil dictator in Eastern Europe.

Cristian risks everything to unmask the truth behind the regime, give voice to fellow Romanians, and expose to the world what is happening in his country. He eagerly joins the revolution to fight for change when the time arrives. But what is the cost of freedom?

Master storyteller Ruta Sepetys is back with a historical thriller that examines the little-known history of a nation defined by silence, pain, and the unwavering conviction of the human spirit.

This YA historical fiction book was a page turner and I could hardly believe she was writing about 1989 as it was so reminiscent of Stalin’s Russia. Highly recommend.

I was immediately sucked into this book. Maybe it was the short chapters (I am a fan of short chapters) but I was always left wanting to read more. It is so well written, and characters are well developed. I am embarrassed to admit I knew next to nothing about this period in history. I was a sophomore in college in 1989 and wasn't aware of anything going on in the world.

This young adult novel is a wonderfully written book about communism during the Cold War.
