Tom Swift and His Flying Lab by Victor Appleton II
Let's go back to 1954 for the first in the rebooted YA science series. The Tom Swift Jr. books are a spinoff from the earlier Tom Swift juvenile science based adventures. In the original Tom Swift books (first published in 1910), the young inventor was pushing the science of the day, with his motorcycle, airship, and airplane. So the science bar had to be raised in the mid 1950s. Tom Swift Jr., starts his adventures with an atomic powered VTOL aircraft that includes a full set of science labs, a kitchen for their cook, Texan "Chow" Winkler, and a smaller set of aircraft (jet and helicopter) in a hanger bay. Good fun, with a definite Cold War setting.
There Will Be Dragons by John Ringo
This is the first book in John Ringo's four book Council Wars series. He wanted to to a science based fantasy series. So this series is set in a far future, in a technological utopia. People live for centuries, they can transform themselves into mermaids, whales, humanoids capable of flight, unicorns, etc. Prety much limited by imagination. There are also fantasy creatures created by genetic engineering and nanotechnology, including dragons and Elves. The Elves were designed as ultra-efficient combat troops. Pro-tip, do no screw with the Elves. Of course, things are not perfect in a Ringo 'utopia'. The human population is shrinking, mainly because raising kids is a chore, and a twenty year commitment. The closest thing to a government is a "Council" that have control over "Mother", the massive AI that controls the planet, and makes the utopia possible. The Council disagrees with how to handle this problem, so one side decides to kill the rest of the Council in order to gain control. The attempt failed, and the resulting conflict between the Council members sucks up all the available power, reducing the rest of the humanity to pre-industrial levels. Mother still enforces her basic protocols, absorbing all energy higher than low pressure steam. Ringo achieves what S.M. Stirling did in his "Dies the Fire" series, by evoking Clarke's Third Law. I've recently reread all four books. It's a fun read. Check it out.
The Guns of Avalon by Roger Zelazny
The second book in the Amber series. Two sets of five books, plus a fist full of short stories and an amazing amount of fan fiction. Prince Corwin has escaped the Dungeon his brother Eric threw him, with the help of the family madman Dworkin. Revenge, and the throne, are what he is after. First he has to go to Avalon, and of course is sidetracked by Lorraine (name of the land and the woman). He does manage to finally get to Avalon and get what he wanted there. Not without complications, including his extremely deadly brother Benedict, another family member named Dara, and the ominous Black Road. This series are amazingly well written, and this volume includes some insight from a guard in the Castle Amber dungeon named Roger.
