See you this weekend and THANK YOU for your support! This will be our best year ever! - Oni, Harknell, and the Onezumi Events Staff


Intervention 7 in Review

Reviews, blogs, and podcasts are pouring in from our attendees, and we’re loving all the feedback we’re getting! If you missed our event this year, these bloggers have got you covered!


‘Intervention was very close to my cave, and even though the DC metro area has some fairly large conventions and festivals, it was amazing to find such an intimate community right here.’

First up, writer Timothy Johnson tells us about his time as a panelist on Intervention Sunday. Check out his summary here, and be sure to check out his website for info on his writing career and his novel, Carrier.


‘What separates this Con from similar ones is the positive, all-inclusive vibe.’

Hello Talalay gives us an overview of the sights and sounds of this year’s event as Sarah Talalay stopped in to see panels conducted by her sister Rachel! Check out Sarah and James’s full blog to follow then on their travels around the world.


‘That’s the magic of Intervention: sometimes even the people who run it don’t know what sort of little miracles are going to happen.’

Our community manager Kara Dennison contributed a staff’s-eye view of the event to We Are Cult, a UK-based blog focusing on everything from sci-fi and fantasy to vinyl reissues and Hammer horror. Visit their blog for news, reviews, and features devoted to all things cult.


‘While remaining a friendly makers’ space, Intervention has shifted its scope into the broader realms of science fiction and fantasy.’

Gillian Kinney gave a run-down of her experience at various panels, offering insight into the convention’s growth over time. Check out her website for more information about her writing, art, and photography.

And, last but not least, there were kind words to be had in this TripAdvisor review of the Hilton, describing Intervention as ‘a geek’s heaven’!
