Originally published in 1989, decades after previous volumes in the series, this hard-to-find 24th book in the Rick Brant Science-Adventure Stories was reprinted in 2012 with permission of the author's estate, making it possible for fans to read it, and to complete their collections of all 24 books. The reprint has a new cover illustration, featuring a portrait of the author in the background. This copy is Like New, with the dust jacket wrapped in protective mylar. I've also got the authorized reprints of #s 21, 22, 23, and the hardcover reprint of "Rick Brant's Science Projects" listed on eBay.
