Perhaps the most famous of all the Green Lanterns, Hal Jordan put on the lantern's ring for the first time in 1959. A re-envisioning of the original crime-fighting Green Lantern (Alan Scott), created by John Broome in the 1940s, this new Green Lantern was a science fiction adventurer. He battled aliens, giant monsters, wealthy sociopaths out to steal his power ring...and the efforts of his lady love, Carol Ferris, to discover his true identity. As the Green Lantern of the Silver Age of comic books, Hal Jordan captured the imagination of a space-minded society of the '50s and '60s. GREEN LANTERN: THE SILVER AGE VOLUME 1 collects the adventures of Hal Jordan as he takes on the responsibility of the ring and the lantern for the first time in SHOWCASE #22-24 and GREEN LANTERN #1-9.

"MILK WARS" part one! Welcome to the un-event of the year! Kicking off a line-wide adventure, DC's Young Animal collides with the DC Universe to bring you a different kind of crossover. The Doom Patrol has discovered that an interdimensional corporation called RetCo has been stealing stories, reconfiguring them and repackaging them for new markets. Our gang of misfit heroes have felt the touch of this nefarious company, and it has already started to change them. Even scarier, though, is how deeply RetCo has embedded itself into current continuity, using the radioactive milk of psychic cows to quell the more dangerous impulses of the Justice League and turn them into heroes safe for the masses. And to kick this off, RetCo has gone all the way to the top.
