Just a bit more info I remembered. It was during 2010-2012 when I read them. I read them in hardcover format (in book form) and no. 4(?) had the black girl reaching out towards the cover. She had a plain white shirt on that was covered with the blue goop, and she was possessed by it. The last book had ended on a cliffhanger with her rising from the goop. Issue 2(?) featured the main characters around a campfire. This detail is a bit more hazy, but I think at the top of the cover it had a zoom on a male lead with black hair? That last detail may not be very reliable, but I appreciate the help.

The book was about four kids, led by a young black girl, who can travel to a different dimension through a magic(?) movie projector. They are locked out if the projector is off, and they jam it to keep it on with an action figure, which subsequently breaks. There is also blue goop that can possess people and zombify(?) them. It was in the kid’s section of the library, but was a bit creepy for the kids that were there. I really would appreciate it if anyone found it. Thanks!
