THE SCIENCE FANTASY CLASSIC! Out of print for more than a quarter of a century! An American pilot unleashes Ragnarok. He flew over the rainbow — but not to Oz! "Memorable!" The Encyclopedia of Science Fiction. The author of The Star Kings returns! In A Yank at Valhalla, the author's euphonious protagonist, a war-weary aircraft pilot on a scientific expedition in the Artic, helps discover a strangely shaped gold cylinder covered with runic symbols. Flying it back to the mainland he soon finds his plane is being drawn northward by an irresistible force. When he spots a vast chasm in the earth spanned only by a shimmering bridge of rainbow hues, with a noble castle rising on the far side, and a golden-haired Valkyrie on a flying horse being pursued by hideous giants, our hero realizes he may have flown over the rainbow, but he hasn't landed in Oz! When he is rescued by the Valkyrie, he discovers her name is Freya, and although he wasn't planning to fall in love with a warrior-maid and demigoddess, he does. Soon Odin, Thor, Baldur, and the other Norse Gods welcome him into the fraternity of Valhalla, as a brother warrior and reveal the super-scientific secrets that have kept them alive — and hidden — for tens of thousands of years. But what he does not suspect is that he, and his love for Freya, is part of Loki's long-brewed plan to free the sinister giants of Jotunheim, trigger Ragnarok, and bring on the Twilight of the Gods! The Encyclopedia of Science Fiction calls A Yank at Valhalla one Hamilton's most "formidably composed" novels, "dark in texture," "one of the novels for which he will be remembered.

Nearly a century before the racks of mass-market books were flooded with media tie-ins for franchises such as Star Trek, Star Wars, etc. (and ten years before E.E. "Doc" Smith created the Lensmen), Edmond Hamilton pioneered and popularized the concept of a galactic peacekeeping force. Hamilton's first crack at the concept in "Crashing Suns" has his band of heroes confined to the solar system as the "Interplanetary Patrol." With "The Star Stealers," Hamilton takes his notion of a stellar police force to the distant cosmic shores as the "Interstellar Patrol."
