An original sci-if title adapted into historical fiction:

Europe has already been devastated by one Great War, which threatened to destroy both the morale and families of English, French, German, and all Western people. Now, these great nations face a second war threatening to be even greater than the last; to make sure they win the next encounter, the English government is breeding and collecting young geniuses to help counter the Axis powers. In school, these young men and women’s training takes the form of competitive games.

And is he careful enough to not kill himself in the process?
