I know Elly wasn't exactly leaving things to fate when she reconstructed Mike's Stone[d] Season and tried to have it published as her own work--let alone causing the whole time warp. But it's not out-of-character for her to be self-contradictory.
Mind you, this does not mean they're in our time. It's just pure coincidence that the reading in question and book in question sound so similar to a reading and book we've heard about recently. And the author and illustrator aren't the same author and illustrator, but they have obvious similarities. :)
