I urge everyone to pick up Aquaman #54. But not for the reason you might suspect. It's because Aquaman #54 is the first appearance of a tribute character in memory of Leah Adezio, who passed away early this year. This Leah will be giving guidance to Garth, aka Aqualad/Tempest, the character that Leah loved deeply all her life.
I don't think the current Aquaman title can be saved from cancellation, but if everyone whose life was touched by Leah bought a copy of each of the next few issues to remember her, it would surely go out with a bang.
