After killing Tom Cruise then killing him again (and again) in Edge of Tomorrow, director Doug Liman plans to stick around the sci-fi genre.

According to The Hollywood Reporter, the filmmaker has been hired to adapt Philip Reeve's upcoming children's book Railhead for Warner Bros. and Di Novi Pictures. It takes place in a future world where travelers get around space via trains that pass through portals. The protagonist is a thief who's hired to steal an object that turns out to be of a higher value and significance than he ever imagined, leading to a great adventure with galaxy-spanning consequences.

There's no word on when Railhead will enter production. The book hits shelves in fall 2015.
