Jensen is currently without an agent and also without a contract. In fact, she doesn't even have a Facebook or Twitter account.
What she does have though, is www.scarletfuries.com, the band that Robert Holmes, her husband started. You can contact them via their site, ask for GK4 to be Kickstarted and also tell them what a fine idea it would be if they covered the soundtrack. It's the most direct way to Jensen's ear. Schafer broke 3 mil in a month, Wasteland 2 just broke a million, there's a revolution happening in terms of what can and cannot be published.
