In August 2010 (issue #600), J. Michael Straczynski took over the series' writing duties and introduced Wonder Woman to an alternate timeline created by the Gods in which Paradise Island had been destroyed and the Amazons scattered around the world. In this timeline, Diana is an orphan raised in New York. The entire world has forgotten Wonder Woman's existence and the main story of this run was of Diana trying to restore reality even though she does not properly remember it herself. A trio of Death Goddesses called The Morrigan acted as the main enemy of Wonder Woman. In this run, Wonder Woman wears a new costume designed by Jim Lee. Straczynski determined the plot and continued writing duties until Wonder Woman #605; writer Phil Hester then continued his run, which ultimately concluded in Wonder Woman #614.
One of the things I love about event comics is that sometimes even a middling to bad event can lead to a great spin-off or post event tie in. Day of Judgement gave us J.M. DeMatteis's run on The Spectre. Infinite Crisis gave us Jeff LeMire's great run on Superboy. While not a new series, Dark Nights Metal allowed James Robinson to have the near perfect ending to Jason's story in Wonder Woman.
In one episode, a newspaper editor named Brown, desperate to discover Wonder Woman’s past, assigns a team of reporters to chase her down; she easily escapes them. Brown, gone half mad, is committed to a hospital. Wonder Woman disguises herself as a nurse and brings him a scroll. “This parchment seems to be the history of that girl you call ‘Wonder Woman’!” she tells him. “A strange, veiled woman left it with me.” Brown leaps out of bed and races back to the city desk, where he cries out, parchment in hand, “Stop the presses! I’ve got the history of Wonder Woman!” But Wonder Woman’s secret history isn’t written on parchment. Instead, it lies buried in boxes and cabinets and drawers, in thousands of documents, housed in libraries, archives and collections spread all over the United States, including the private papers of creator Marston—papers that, before I saw them, had never before been seen by anyone outside of Marston’s family.
