"Frohock has intricately woven a unique reinterpretation of history. Eloquent prose accompanies a lyrical theme amid prewar tensions, enriching this imaginative historical fantasy." -- Publishers Weekly (starred review) In this sequel to Where Oblivion Lives, the first entry in the Los Nefilim series set during the Spanish Civil War, a coded notebook containing the identities of Los Nefilim's spies falls into enemy hands, and Diago is faced with an impossible choice: betray Los Nefilim or save his family. February 1939 Catalonia has fallen. Los Nefilim is in retreat. With the Nationalist forces hard on their heels, the members of Los Nefilim--Spanish Nephilim that possess the power to harness music and light in the supernatural war between the angels and daimons--make a desperate run for the French border. Diago Alvarez, a singular being of angelic and daimonic descent, follows Guillermo and a small group of nefilim through the Pyrenees, where the ice is as treacherous as postwar loyalties--both can kill with a single slip. When a notebook of Los Nefilim's undercover operatives falls into a traitor's hands, Diago and Guillermo risk their lives to track it down. As they uncover a pocket realm deep within the Pyrenees, Diago discovers his family is held hostage. Faced with an impossible choice: betray Los Nefilim, or watch his family die, Diago must nurture the daimonic song he has so long denied in order to save those he loves.
