Batman and the Villainous Voyage (The Dark Knight Series)

A charity cruise filled with GOTHAM'S wealthiest citizens has been boarded by not one but two groups of hijackers! POISON IVY and MR. FREEZE fight for the right to ransom the passengers with countless citizens caught in the crossfire. Outnumbered and out of his element, BATMAN will have to find a way to play one group of crooks against the other, or they’ll all go down with the ship.
