In New Orleans, nocturnal wildlife rescuer Emmett Landry brings home an injured black bat after a storm. His stubborn little patient seems to understand every word, refuses to leave his side, and becomes fiercely jealous whenever another man gets too close. Emmett soon discovers that the bat is Bastien Valcourt, the dangerous heir to an ancient vampire family. An unexpected blood bond makes Emmett the only person capable of calming Bastien and helping his poisoned body recover. Drawn into a hidden supernatural world, Emmett agrees to care for him—but Bastien soon wants far more than recovery. What begins as a rescue gradually becomes an irresistible romance between a patient human caretaker and the possessive vampire who refuses to let him go.
