Arkham City: The Order of the World (Arkham City: The Order of the World #4)

Dr. Joy is now face to face with the ghost of Amadeus Arkham - the ghost that she had assured all her patients did not exist. Now faced with overwhelming evidence that the Ten-Eyed Man’s “delusions” were anything but, she has found herself questioning everything. Meanwhile, Dr. Phosphorus and Nocturna attempt to live a “normal” life in Gotham, but the good doctor’s radioactive body may be having unforeseen side effects on their unsuspecting neighbors.
