John currently lives in Pittsburgh, Pennsylvania, with his brilliant English wife Deb. She keeps his life fun and bright while he writes about the dark and macabre. He might be a Boomer, but he feels more like a late-Millennial.

John is the first son of Jack (John P., Sr.) and Willie (Dwillis) Wallman. He has a brother Mark, and a sister Mary Louise whom everyone calls Mimi. He enjoys visiting his twin sons, Lance and Drew, and their families—especially his grandchildren.

He’s an avid tennis fan and a pretty good player. He loves a good dark fantasy, and he’s a die-hard Star Trek aficionado.

John has worn a few hats throughout his adult years—from teaching to human capital management to the nuclear industry to corporate retail.

Most of his energies, however, are spent in the universe of The Dark Matter Series, writing about reluctant heroes and angels and vampires and other dangers. The Dark Stirs, the first book of the series, is his debut novel.
