Justice League Vol. 4 #52
“The Garden of Mercy” part two of two! For the first time, the Justice League explores the planet of the Black Mercy’s origin. One flower is enough to incapacitate even the strongest hero, but with an entire planet full of them, the Justice League must steel their minds or else succumb to the withering effects of the great tree at the core. With Batman unable to cope, can Superman, Wonder Woman, the Flash, and Green Lantern survive the horrors of their souls?
