Reši jo ženska, ki jo vidi kot angela in ki zaceli njene rane ter ji podeli dar večnega življenja – tako, da jo spremeni v vampirja.Sever Španije proti koncu 19. stoletja. Med zadnjimi dnevi dokončne vojne karlističnega režima hudo poškodovano deklico iz bombardirane sirotišnice reši skrivnostna ženska, ki živi globoko v gozdu. Mlado dekle na robu smrti jo vidi kot angela, ki jo je prišel odnest v nebesa. A kmalu ugotovi, da ji je v resnici podelila dar večnega življenja – tako, da jo je spremenila v vampirja. Nima druge možnosti, kot da sprejme svojo usodo; naučiti se bo morala življenja v sencah in osamljenosti, večno ujeta v telo deklice. Neskončno število lun gre mimo in nekega dne spozna Cándida, skromnega moža, ki jo vzame k sebi, kot bi bila njegova edina hči. Pred njo je zdaj nova, drugačna pot.
