From the moment Louisa first catches sight of the strange man who occupies a forbidden room on the thirty-third floor, she is determined to befriend him. Unbeknownst to Louisa, he is Nikola Tesla--inventor of AC electricity and wireless communication--and he is living out his last days at the Hotel New Yorker. Winning his attention through a shared love of pigeons, she eventually uncovers the story of Tesla's life as a Serbian immigrant and a visionary genius: as a boy he built engines powered by June bugs, as a man he dreamed of pulling electricity from the sky. The mystery deepens when Louisa reunites with an enigmatic former classmate and faces the loss of her father as he attempts to travel to the past to meet up with his beloved late wife. Before the week is out, Louisa must come to terms with her own understanding of love, death, and the power of invention.--From publisher description.
