Emil Aron Dorph

Appointed to teach the Grand Duchess's timid son the intricacies of seduction, a love connoisseur finds himself in a scandal — and a romance of his own.

Erna disguises herself as a man to take the place of her intellectually disabled son, Kalle, who has been called to the front. She goes to war in his place. In the trenches, she rediscovers love.
