Invasion — Luke Rhinehart

Super-intelligent furry aliens suddenly appear from another universe. And they've come to earth to have fun. “Louie” follows fisherman Billy Morton home one day and he and his family come quickly to love the playful alien. But when Louie starts using their computer to hack into government and corporate networks, and steal millions from banks to give to others, they realize that Louie and his friends mean trouble. Billy, his wife and two sons begin a roller-coaster ride of fame, fortune, jail, death, resurrection, and a distinguished ranking high on the FBI's “Most Wanted” List.

The Government soon decides that all these aliens are terrorists. They must be eliminated. The aliens are playing games they hope will help humans to see the insanity of the American political, economic and military systems. But the Powers that Be don't play games: they make war.
