"A nifty combination of police procedural and urban fantasy." — Charlaine Harris, #1 New York Times bestselling author
"Mark of the Demon crosses police procedure with weird magic. Diana Rowland's background makes her an expert in the former, and her writing convinces me she's also an expert in the latter in this fast-paced story that ends with a bang."
— Carrie Vaughn, New York Times bestselling author of Kitty Raises Hell
"Rowland’s world of arcane magic and demons is fresh and original...[and her] characters are well-developed and distinct.... Dark, fast-paced, and gripping."
"With each new chapter in this mesmerizing UF series, the gifted Rowland constructs her world and adds depth to her characters, all while giving readers clues to the over-arching plotline." — RT Book Reviews
