It's a cosmic adventure beyond your wildest imaginings: Power Girl and Harley Quinn, stranded in a forgotten dimension, on the homeworld of the amorous warlord Vartox! They'll sacrifice anything they have to in order to get home...except their dignity! Kidding! That'll be the first thing to go.
This new series puts together two of DC Comics's most unlikely allies in their first ever team-up series. HARLEY QUINN AND POWER GIRL, from the same creative team as the NEW YORK TIMES bestselling series, collects issues #1-6.
