Pablo Tomas, the heir, lives as an unemotional and detached observer, incapable to claim his destiny. The death of his grandmother takes him to Isclacerta, the family mansion built by his great-grandfather, a legendary millionaire. There, Pablo will be submerged in the testimonies of his predecessors and will understand that he belongs to a chain that is new and surprising to his usual way of life. The questioning of identity, the discovery of a dark past, and a peculiar history of the Spanish 20th century, are the bases on which the author constructs this exciting family saga.
