Summary: Time is running out for planet Earth. An insidious Martian plague has been infecting the planet for over twenty years, and has resisted all human efforts to eradicate it. With global extinction now imminent, the only possible solution left is to directly access Martian technology by a daring space mission–to the moon first and then Mars. But how feasible is the ambitious plan to send astronauts into space in 1945? Will the super-weapon, hidden by the Martians at the lake on the moon, hold the desperately needed cure for mankind's survival? Can it really be used to instigate the future of another timeline on Earth? The stakes are high and so is the risk of contact and conflict with Martians, but one astronaut unknowingly holds the key to the evolution of the Martian race and the reason why the aliens came to Earth in The War Of The Worlds. Gateway To Mars is the third volume of The Martian Diaries series that continues the classic H.G. Wells Mars novel in a compelling, unmissable action adventure. If you're a fan of The War Of The Worlds you won't want to miss this story of survival, despair and hope, so get your copy today! What readers have said: “A really well written, excellent continuation of the story and a truly brilliant tribute to HG Wells!

Summary: Lida was their last chance for an uncolonized planet. But a world-spanning fungus had colonized it first. Agetha and her husband have spent their whole lives in the fleet’s zero-G. Now all is turmoil as the fleet lands, discovering they are surrounded by a single fungal biomass spanning the entire planet. To build a new home, the fleet must confront a dangerous organism, and Agetha must decide if she can raise a family in this inhospitable landscape. Jane Brighton holds tenuous command over the colony and its administrators. She and the other gene-modded leaders emerged from their four-hundred-year suspended animation to find a crew much different from the one that departed Old Earth. Jane must direct the colony’s fragile growth and defend it against being overrun by the fast-growing biomass. But there is something none of the colonists know. The massive organism that spans the planet is not simply a fungal mass, nor even a chimerical combination of species that once roamed the planet. The biomass has desires and goals, and one is to know these strange beings carving out a home in its midst. Download today to read of the colony’s fate in Of Mycelium and Men!

Summary: Nothing is new under another sun. Not even murder. This mission should be simple. Exoplanetary scout Leif Grettison and ace pilot Yang Yong are off to deliver a load of supplies and reinforcing settlers to a recently colonized planet. It’s as routine as a starflight can be. Famous last words. Something is wrong with the colonists. They are astonishingly ill-suited for the task of settling a new world. The planet, too, is a poor place to plant a town for humans. Even if everything goes right, the colony might not survive. Then one of the colonists is found dead. Murder is a possibility. Not long after, another one dies—and this time, it’s definitely murder. In a world with only two hundred people, there’s at least one killer. Meanwhile, the colony’s new leader has a plan—but Leif has doubts. Will this man save the settlement, or use his power to become a dictator? Leif and Yong’s mission is clear: they must leave the colony in shape to survive. Leif is a retired soldier, not a detective, and when it comes to investigating a crime, he doesn’t have a clue. Literally. Still, it falls to him to follow the evidence and find the killer. He also needs to deal with the leader and the leader’s plan. If Leif fails, the only mystery may be how long it will take for everyone to die.
