Jeph Loeb and Tim Sale have formed one of the most highly-regarded partnerships in comics with works including BATMAN: DARK VICTORY and BATMAN: THE LONG HALLOWEEN. But their first collaboration was a miniseries for DC that rescued a classic property from near-obscurity: THE CHALLENGERS OF THE UNKNOWN. Four men who barely survive the crash of a small aircraft now consider themselves to be living on borrowed time! Because they managed to avoid such a devastating fate, they dedicate themselves to a life of harrowing adventures, all in the name of good! Nothing is deemed too dangerous for the Challengers--after all, they should be dead already.
