Sapphire Sparks Katie Dunn

Jo Maski is prepared for anything. Banshee? Check. Vampires? Check.

Blue lightning shooting from her fingers? Uh, not check.

When she saves her superhero sister from monsters, she joins the House of Mystery to learn more about her strange and quite unhelpful new powers. For some reason, the energy she releases helps monsters instead of disabling them. That could not have happened at a worse time. Monsters are appearing more frequently and heroes are disappearing.

But don't worry. She may not have a superhero name yet, but she does have her tactical backpack and a mysterious and handsome stranger to help her figure it all out.
