★★★★★ “Move over Daniel Silva, James Patterson, and Dan Brown.”
—Chip Polk, Review for The Atlantis Riddle

— Shana Tehan, Press Secretary, U.S. House of Representatives
★★★★★ “I discovered Kevin Tumlinson from The Creative Penn podcast and immediately got his novel, Evergreen. I read it in like 3 seconds. It’s the most fast-paced story I’ve encountered.”
—R.D. Holland, Independent Reviewer
★★★★★ “Comparison to Clive Cussler is a natural, though Tumlinson’s ‘Dan ‘ is more like Dan Brown’s Robert Langdon than Dirk Pitt.”
