This is based on the two books written by S.M.Stirling which are The Sky People and the recently published In The Courts of the Crimson Kings.
To give a brief synopsis of this setting, these books mix two generes, basically a Pulpish Venus and Mars mixed into a hard science background, using the filter of an alternate history persective. The explaination is that in this alternate universe aliens called "the Lords of Creation" terraformed the planets Venus and Mars using Earth Lifeforms, and their presence has been more or less continous up until about 10,000 BC. These aliens have left very few artifacts of themselves other than the planets they terraformed. These planets have been terraformed such that their new statistics are as follows:

Venus in typical Pulpish fashion is a Jungle World filled with dinosaurs and "cave people", basically of two varieties Homo Sapiens, and Neandertals. The Dinosaurs are the usual menagerie you would expect beginning with the ones found on Earth in 200 million BC through the late Cretaceous (65 million BC), there are other prehistoric animals here as well, mastodons, sabre-toothed tigers, Pterodons, giant carnivourous birds etc. There is a US and Soviet Base on the planet. The US is accompanied by other smaller bases in its immediate vicinity consisting of its allies in the Westbloc, while the Soviets have their Allies/Subjects of the Eastbloc near their base on the other side of the equatorial continent. The inhabitants of Venus are primitive, with their most advanced nation being the equivalent of Earth's bronze age.
Mars in typical Pulpish fashion has the flavor of E.R. Burroughs Princess of Mars series or Barsoom novellas. Mars is composed of many warring states with various assortments of near-humans, humans, and intelligent non-humans. Mars once had a global Empire ruled by the Ancient "Crimson Kings", that Empire is no more, but a fragment of it still exists under the shadow of the great shield volcano Olympus Mons, there its leaders plot their comeback, and they have a plan to regain their past glory, with the help of some unwitting Earth Humans from the Soviet Union Circa 2000 AD.
The Martian's technology is a bit unusual, they rely on biotech - "living machine" devices. All of their advanced technology above the medeaval relies on a "living machine" device, their guns are animals shaped like guns which they feed a bullet and some food, the creature expells methane in a chamber behind the bullet and when the trigger is pulled a spark ignites the methane propelling the bullet at lethal high velocities out the muzzel. Since the gun is a living creature, it reproduces and heals itself instead of requiring manufacture and maintenance. Similarly the Martians have a "Land Boat" which is a sailing ship on wheels, the wind pushes the boat around, which can tack into the wind much like a water craft can, its wheeled suspention system is controlled by a series of muscles which dip the wheels into pits and over boulders, providing a relatively smooth ride for those on the deck of the boat. The ship has sails and its living suspention system is fed regularly. Another nifty item the Martians have is a set of binoculars which attaches to the user's head and drinks some of the person's blood, in return it connects to the user's optic nerve, feeding enhanced vision directly to the person's visual cortex. There are undoubtably versons that have night vision or thermal imaging capabilities, but as in the above, all this technology is grown rather than made. Also it seems, the Martians didn't invent this technology, but simply use it, whoever gave it to them or taught them to use it is unknown, it goes all the way to the beginning of the Martian recorded history, which stretches back for about 30,000 years. Martians have been building cities while Earth humans were still hunter-gathers living in caves.
The rest of the Solar System, is otherwise like our own Solar System. Mars has two moons, Phobos and Deimos which are in their usual orbits and appear much as we see them.
On Earth, historical events departed significanly from our own most significanly in 1947, when Astronomers discovered that Mars and Venus had oxygen in their atmospheres. Otherwise Venus is covered in a layer or perpetual clouds, in this case water clouds. Most significantly is an upper layer of cirrus clouds composed of ice crystals. Unlike Earth where the cirrus clouds consist of thin wisps in an otherwise clear blue sky, the Venusian cirrus clouds cover the whole sky, obscuring surface features from space and diffusing and reflecting half the sunlight away from Venus's surface, keeping it cooler that what it would otherwise be. What maintains this perpetual cloud layer is somewhat perplexing to Earth meterologists who have yet to come up with a satisfying explaination. Venus looks otherwise like a bland white disk when seen from Earth.
In the case of Mars, the canals are real, there is an ocean in the Northern Hemisphere called the Northern Ocean , and a smaller Southern Sea called the Antartic Ocean in the Hellas Basin, otherwise 75% of Mars is land, its atmosphere is thinning and its surface is drying and getting more arid, leaving the deserts dotted with abandoned cities along dry canals. The United States and Allies maintian their Embassies on Mars, consisting of a total of 100 people, all shipped very expensively from Earth via nuclear rockets, the Soviets and Eastbloc nations have a simular embassy. For the US and Western Alliance the U.S.A. Space Force provides most of the transportation services, this fifth branch of the Defense Department was established in the 1950s shortly after it was discovered that there was life on Mars, and particularly after the canals were confirmed and cities were imaged by US and Soviet Space probes, in a race to get to Mars first, rocket development was accelerated and the space age began early in the 1950s as opposed to 1957 in our timeline. The Cold War still rages, but it is much calmer, mostly involving spies and espionage, rather than brush fire wars breaking out. The Superpowers have mostly turned their attention to the two planets rather than in fomenting and suppressing revolution and rebellion in the Third World.
