From the back of the book: On a towering pinnacle of rock, at the foot of a mountain pass, stands the Castle of Flowers. It sounds like pleasant spot in this rugged land at the northern frontier. But even though it may have been beautiful once - now it's just a place of nightmares... The rare plants that the old botanists nurtured long ago have turned into intelligent killers - hungry for blood. Their clutching, poisoned tendrils attack all intruders. For they are the guardians of the castle - and of the helpless prisoner inside it. A desperate rescue mission must be attempted, and YOU have been chosen to undertake it. Do you dare enter the Garden of Madness to discover the horrors that lie in wait within the fortress itself...?
