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 than 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 it 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.
When Alex begins to investigate the blood bank, he suspects that the people in those white lab coats are not actually doctors. I mean, what doctor is afraid of a bulb of garlic…
It turns out some people are more BLOODTHIRSTY than others.
Don't come snivelling to Annie if you're sorry you ever opened this book … You've been warned!
