(W) Robert Venditti (A) Xermanico (CA) Gary Frank. "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?
