Wonders of the Invisible World starred Library Journal review
"A researcher goes back in time to visit Cotton Mather and finds the preacher’s visions are not what he expected in the title story of McKillip’s (The Bards of Bone Plain) latest collection of mesmerizing short fiction. From the deliciously macabre retelling of “The Twelve Dancing Princesses” to the elegant story of courtship and obsession depicted in “The Kelpie,” the 16 stories collected here display the author’s talent for creating tales both delicately beautiful and heartbreakingly cruel. The text of her Guest of Honor speech at WisCon 2004, included within, offers valuable insight into the mind of the writer. VERDICT: Any collection of McKillip’s short stories will be a valuable asset to any library and a joy to her many fans."
