Sometime in the mid- to late-2000s, I recall reading a sort of urban-fantasy YA novel (or perhaps series?) that involved a parallel world where lost objects end up. I initially had it mixed up with memories of The Seems series, but after asking for help identifying that one I'm thinking it was probably a different book. This is what I remember of it:
- There's a parallel world where lost items frequently end up
- There's a barrier between the worlds that on the earth side is invisible, fragmented, and small bits of it move around erratically (the barrier moving through objects and taking them to the other world is how things get lost)
- On the otherworld side of it, the barrier is visible, stationary, and solid, and there are people whose job is to take items back through so they can be found
- There might be something related to TVs or TV static? I don't know any more about what it was but for some reason I keep thinking of something like that
Any help identifying this would be appreciated!
