About The Seam by A. M. Vesp:
Nina has spent eleven years refusing to print anything she couldn’t verify. Then her brother Daniel — a physicist who stopped answering his phone — leaves behind a question that can’t be fact-checked: what if, behind an ordinary door in an ordinary building, our world touches another version of itself? What begins as a missing-person story becomes an investigation into the seam between worlds, the people appointed to guard it, and the price of looking through. FREE on Amazon September 10-13.
