The Boy from Reactor 4 (Nadia Tesla, 1)

Nadia’s memories of her father are not happy ones. An angry, secretive man, he died when she was thirteen, leaving his past shrouded in mystery. When a stranger claims to have known her father during his early years in Eastern Europe, she agrees to meet—only to watch the man shot dead on a city sidewalk. With his last breath, he whispers a cryptic clue, one that will propel Nadia on a high-stakes treasure hunt from New York to her ancestral homeland of Ukraine. There she meets an unlikely ally: Adam, a teenage hockey prodigy who honed his skills on the abandoned cooling ponds of Chernobyl. Physically and emotionally scarred by radiation syndrome, Adam possesses a secret that could change the world—if she can keep him alive long enough to do it. A twisting tale of greed, secrets, and lies, The Boy from Reactor 4 will keep readers guessing until the final heart-stopping page.
