My review of Everfree by Nick Sagan was just published in Science Fiction Weekly. I interviewed Nick too, and that should be published over there some time soon as well. 

[Excerpt:] Readers new to Nick Sagan’s work probably have some lofty expectations. His father, the world-renowned Carl Sagan, was both a brilliant scientist and the author of many books, including the terrific SF novel Contact. So he clearly has the genes for good writing and smart science; the question is, does he live up to expectations? The answer is yes and then some, and luckily for SF fans, the younger Sagan has his father’s gift for storytelling, but has chosen to devote his life not to writing science but to writing science fiction.
