An evil so profound it threatens all mankind... the mightiest heroes on the planet uniting to defend us all... a secret crisis of such utter finality that a countdown to civil or infinite war seems unavoidable... but have you ever wondered what really happens during Crossovers? This volume collects all six issues of the first-ever Boys spin-off mini-series by Garth Ennis and John McCrea, with covers by co-creator Darick Robertson.
