In the August issue of Locus Magazine, Gardner Dozois reviews Oz Reimagined:
“The stories here can be sorted out into three main categories: stories that take the mythology of Oz seriously and treat it with respect, even while tweaking it in various clever ways; stories that reinvent the Oz mythology in the language of another genre or another culture […] ; or stories that set out to deliberately demythify Oz, giving us a cynical, hard-edged, revisionist modern take on it, demonstrating that the dream has died, if it ever existed in the first place.”
He adds “The best stories here are probably Tad Williams’s ‘The Boy Detective of Oz: An Otherworld Story’ […] and Jane Yolen’s “Blown Away.” […] There’s also good work in Oz Reimagined by Orson Scott Card, Seanan McGuire, Simon R. Green, Theodora Goss, Dale Bailey, Jonathan Maberry, and others.”
Then, summing up, he says “A solidly entertaining anthology, and worth a read.”
