Batgirl and Robin team up with Man-Bat to take on the recently returned Outsider... who uses the Sunset Gang and a were-jaguar to wage war against the heroes!

Not a dream! Not a hoax! Not an Imaginary Story! The three stars of The Batman Family finally team up in a book-length novel, against the one supervillain nobody expected them to fight!

Also of note is a 1-page montage of reader-submitted redesigns for Robin's costume, one of which was provided by Norm Breyfogle.
