Bruce Coville knows his audience. His popular middle-grade anthologies featuring ghosts, monsters, magic, and other frightful and fascinating topics have long brought together the very best writing in a given genre. Now he turns his attention to science fiction featuring alien visitors and wily shapeshifters in two gripping new collections. Each anthology includes more than a dozen entries by master storytellers like Ray Bradbury, Lois Tilton, Lawrence Watt-Evans, and Jane Yolen. Each story is a window into another world; to read one is to be transported, if only for a brief time, to somewhere else entirely.
