Based on the true life of Ludwig (Lale) Sokolow, Heather Morris's novel is a testament to the human spirit and the power of love to blossom even in the darkest places. And it is difficult to imagine a darker place than the Auschwitz/Birkenau concentration camp. In 1942, Lale, like other Slovak Jews, was sent to Auschwitz. Once there, thanks to the fact that he speaks several languages, he gets a job as a tattoo artist and fills numbers for new prisoners with terrifying speed, and for this he receives some privileges: a separate closet, slightly better food and relative freedom of movement around the camp. One day in July 1942, Lale, prisoner 32407, puts the number 34902 on the hand of a trembling young woman. Her name is Gita. Despite their difficult situation, despite the fact that every day could be their last, they fall in love and, against all odds, believe that they will be able to survive in these inhuman conditions. And although Lale’s position as a tattooist is relatively better than that of other prisoners, it does not protect him from the cruelty of the SS. Again and again he risks his life to help his fellow sufferers and especially Gita and her friends. Despite the constant threat of death, Lale and Gita never stop believing in the future. And in this future they will definitely live together happily ever after...
