On a cold spring night in 1952, a huge meteorite fell to earth and obliterated much of the East Coast of the US, including Washington, DC. The ensuing climate cataclysm will soon render the Earth inhospitable for humanity, as the last such meteorite did for the dinosaurs. This looming threat calls for a radically accelerated effort to colonize space and requires a much-larger share of humanity to take part in the process. Elma York’s drive to become the first lady astronaut is so strong that even the most dearly held conventions of society may not stand a chance against her.

Mary Robinette Kowal continues the grand sweep of alternate history begun in The Calculating Stars. The Fated Sky looks forward to 1961, when mankind is well established on the moon and looking forward to its next step: journeying to, and eventually colonizing, Mars. Of course the noted Lady Astronaut Elma York would like to go, but there’s a lot riding on whoever the International Aerospace Coalition decides to send on this historic - but potentially very dangerous - mission. Could Elma really leave behind her husband and the chance to start a family to spend several years traveling to Mars?

One summer weekend in 1949 - but not our 1949 - the well-connected "Farthing set", a group of upper-crust English families, enjoy a country retreat. Lucy is a minor daughter in one of those families; her parents were both leading figures in the group that overthrew Churchill and negotiated peace with Herr Hitler eight years before....

This book is considered a prophetical novel foretelling the advent of nuclear weapons. A constant theme in Wells’ work, such as his 1901 nonfiction book Anticipations, was the role of energy and technological advance as a determinant of human progress. The novel opens with this: "The story of mankind is the history of the attainment of external power. Man is the tool-using, fire-making animal...."

The tale again comes to us from the pen of Murgen, Annalist and Standard Bearer of the Black Company. Led by the wily commander, Croaker, and the Lady, the Company is working for the Taglian government, but neither the Company nor the Taglians are overflowing with trust for each other. Arrayed against both is a similarly tenuous alliance of sorcerers, including the diabolical Soulcatcher, the psychotic Howler, and a four-year-old child who may be the most powerful of all.

The invaders are coming; the Posleen, a seemingly unstoppable horde who have conquered one star system after another, literally feeding on their conquests. Earth's dubious allies, the Darhel, have given the humans a number of highly-advanced technological devices, including a process for rejuvenating the aged, including trained and proven soldiers who otherwise would be too old to fight. Rejuvenation may give a critical edge, since to survive, the Earth must use every resource at hand.

The more bodies emerge, the more the gang suspects that there is dangerous magic at work.

Their pleasure is overshadowed by a brilliant but unbalanced druid who knows a perilous secret about Maeve's past. The prequel to The Passion of Mary Magdalen.

This book is a stimulating and entirely plausible insight into how Hitler and his generals might have defeated the Allies, and a convincing sideways look at the Third Reich's bid at world domination in World War II. What would have happened if, for example, the Germans captured the whole of the BEF at Dunkirk? Or if the RAF had been defeated in the Battle of Britain?

After being commissioned to find a rare book, Librarian Irene and her assistant, Kai, head to Prohibition-era New York and are thrust into the middle of a political fight with dragons, mobsters, and Fae.

On May Day 2018, 60 meteors entered Earth's atmosphere and exploded around the globe with a force greater than a nuclear blast. Earthquakes and tsunamis followed. Then China attacked Europe, Asia, and the United States in the belief the disaster was an act of war. Washington, DC was a casualty of the meteor onslaught that decimated the nation's leadership and left the surviving elements of the armed forces to try to restore order as American society fell apart.

The Second World War was turned on its head at the moment Admiral Kolhammer's ultra-modern stealth warships were hurled back through time from 2021. But no one could have predicted just how much of a nightmare would ensue.
