Here are the SF/F/H-related April Fool’s Day posts I’ve seen so far:

• Tor Books will publish manga editions of John Scalzi’s fabled fantasy trilogy The Shadow War of the Night Dragons.
• Scott Lynch finds this outrageous, since he feels Scalzi’s trilogy rips off his own The Night Shadow of the Dragon War.
• Readercon’s book club selections are announced.
• Mary Robinette Kowal reveals her true identity.
• Book View Cafe will be publishing some modern classics.
• Blizzard is launching a line of educational games. (h/t Adam Lipkin)
• Jim Butcher announces his next project. (h/t Harry Connolly)
• Jay Lake has something similar in the works. (h/t Harry Connolly)
• Lawrence Watt-Evans has an innovative way of distributing his new story. (h/t Harry Connolly)

Got any others to add to the list?
