The Lost and Broken Memory by Chris M. Arnone Things Forgotten, Book Two

Paperback.
Published July 2017.

Gabriel Drake had it good. Big house in Malibu. Best-selling book about his discovery of the long-lost Babylon. Only, that's not what happened. Gabriel was in another world, the one where all the lost and forgotten places, things, and even people live. Gabriel was flung back to our world, and Babylon came with him. He doesn't remember any of this.

But when Gabriel meets someone else sent back from those forgotten lands, the magics that hold Gabriel's memories at bay start coming unravelled. Now, these magics threaten him, the wildly talented and unpredictable Lorelei, and the entire world. Afraid for his life and sanity, he's being hunted by a mysterious secret society and the authorities want him for a murder he didn't commit.

The world Gabriel forgot is magical and dangerous, but as it turns out, the real world isn't so mundane, either.
