Jeffery Cooper - Nightmare On Elm St Books 4 and 5

Synopsis:
Freddy's back, looking for some 'soul' food. And he 
won't stop even when Kristen Parker - the last child 
of Freddy's killers - goes on a trip that puts her 
six feet deep. Now the fiendish phantom is using 
other kid's dreams to find his victims - and to 
slaughter them in new and ingeniously gory wars.
His blades are razor-sharp, his jokes are improving, 
and he is eternal. Neither can his bloodthirst be 
stopped. Illustrated
