Scared Stiff by Jahnna N. Malcolm

Now HERE is a children's horror book; 2 kids live with their parents in a mortuary and one night when the parents are gone, a new body gets up and starts killing people and attacking anybody who gets in his way for revenge. And I like the ending because while it's not very satisfactory, it does avoid the sappy typical 'oh it was just a dream, oh it never happened, everything's fine, everything's normal' ending a lot of similar stories take. Did any of the 90s kids here read this one growing up?
