*Finest on two worlds.
Before their friendship, before the Justice League and Darkseid, before Superman could even fly, a Batman and Superman were transported to another world by a rogue goddess. In this strange parallel place, where many things are the same, but others are dangerously different, the two greatest heroes on Earth must become a team for the first time. But to get home, they'll also need to team up with Batman and Superman, the two greatest heroes on Earth 2...
From their first meeting to their darkest hour, the two greatest heroes in the world share the spotlight in Batman/Superman: Cross World, from the superstar creative team of Greg Pak, Jae Lee, Paulo Sequeira, Ben Oliver, and Yildray Cinar.
Collects Batman/Superman #1-4 and Justice League #23.1: Darkseid. *Source: back cover.
