This month, io9 read If Then by Matthew De Abaitua. Today, from 3 p.m. to 4 p.m. (Eastern time), he’ll be joining us to answer questions about near future science fiction, writing about war, repeating histories, and anything else you want to know.

Start asking your questions about If Then in the comments now and he’ll answer as many as he can while he’s here. Please be polite!
