Groff Conklin described To Walk The Night as "a subtle, moving story of mood and character, written in the great tradition of British fantasy, even though the author is an American.
"[9] Anthony Boucher praised the same novel for its "rich warm character-drawing, disturbing subtlety, [and] splendid sense of vast beauty in the midst of terror.
"[11] Hartford Courant reviewer George W. Earley praised it as "a wondrous blending of science and occultism guaranteed to unnerve the most blasé of readers.
King wrote, "They are good stories and can be read simply for pleasure, but what makes them fascinating and takes them to a higher level is their complete (and rather blithe) disregard of genre boundaries.
