The Nightmare Club: The Weird Blood Bank by Annie Graves

Welcome to the Nightmare Club, the sleepover that is definitely not for wimps. Annie Graves is your host, and she only invites guests who can tell really creepy stories. Alex gets taken to the doctor more often that Alex likes. Dr White takes an awful lot of blood samples – so greedy is he for blood that he uses a double syringe and he sends great big bottles of if to the ‘lab’. This makes Alex suspicious – and sure enough, the blood ‘samples’ are not going to a lab at all, but to the blood bank. Alex decides to investigate, and it turns out that the blood bank has been taken over by flocks of white-coated vampires!
