This doesn’t happen often enough in m/m books: two MCs you can happily root for and a plot that makes you squirm and hope for a HEA. Pure heaven! Despite the “Hollywood” feel of the story and an abundance of endearments (although I could imagine an aristocrat, even though he’s a high-ranking Wehrmacht soldier, who calls his love interest “Süsser” sort of daringly or ironically or - in the end - lovingly).
I won’t say much more because this review
does a wonderful job already.
