The Sinister Invasion / Operation Terror

Rate this book
Armchair Fiction presents extra large editions of classic science fiction double novels. The first novel, “The Sinister Invasion” is an exciting adventure classic by one of the science fiction genre’s most beloved authors, Edmond Hamilton. It was strange…how easy it was to step right out of your own life, right out of the familiar Earth you’d always known, and into a cosmic mystery! That’s what happened to Ross Birrel, and it all started by opening the door to his own apartment! He soon found himself in the role of a most unlikely undercover agent—an agent with one specific to uncover an alien spy ring right here on Earth. Only it wasn’t that simple, and Birrel soon discovered there was an alien threat far more sinister than anyone on Earth could have imagined. But the key to the mystery depended on whether or not he could trust a female alien—a beautiful woman from beyond the stars who might be a friend to Earth…or its worst enemy. The second novel is “Operation Terror” by sci-fi great Murray Leinster. The radar complex had picked up the strange object in space just as it neared the Earth’s surface. It was described as “an object of considerable size.” The impact of its landing at Boulder Lake Park, Colorado was felt on every seismograph around the world. Then, the first reports began to trickle there were “creatures” on board—creatures who soon left their ship and began exploring the area…Where was the ship from, and what was the quest of the strange visitors—these visitors who were armed with a terrifying paralysis ray that blinded its victims, filling their nostrils with a reptilian odor of the jungle? Only one man in the area could hope to solve the mystery of these aliens—aliens who had come to call Earth “theirs.”

Edmond Moore Hamilton was a popular author of science fiction stories and novels throughout the mid-twentieth century. Born in Youngstown, Ohio, he was raised there and in nearby New Castle, Pennsylvania. Something of a child prodigy, he graduated high school and started college (Westminster College, New Wilmington, Pennsylvania) at the age of 14--but washed out at 17. He was the Golden Age writer who worked on Batman, the Legion of Super-Heroes, and many sci-fi books.

If they had completely different blood types no children would be possible, but they could always adopt an octopus. Don’t know why they would, but they could.

Somehow containing insta-love in a book I picked up because I wanted to switch things up from romance to sci-fi. Quick and yet I did found some good phrases to underline.
