The first part is a well-researched retelling of the years leading up to the Manhattan project and the building of the bomb, through the eyes of Oppenheimer and others. The rest is a science fiction extension of what could have happened if the group stayed together and are faced with another big challenge. I enjoyed the first part even more, as an entertaining way of learning more about Oppenheimer and the other scientists involved.
I reread the tripod trilogy by John Christopher: The White Mountains, The City of Gold and Lead, and The Pool of Fire. Hadn't read them for a while but enjoyed them as always.
Heaven's River by Dennis Taylor is the forth in the Bobiverse series.
Three Laws Lethal by David Walton.
The House of Styx by Derek Künsken took me a while to get into, but then enjoyed it.
The Oppenheimer Alternative by Robert Sawyer. Don't usually like historical fiction but will make an exception for this one.
And for something different, if you want to try rural Australian fiction find anything by Jane Harper, but in particular The Dry and The Lost Man.
I found:
- The Oppenheimer Alternative https://www.amazon.com/Oppenheimer-Alternative-Robert-J-Sawy... (Fission bomb instead of Fusion bomb)
- The Berlin Project: https://www.goodreads.com/en/book/show/30753656 (earlier atom bomb)
