Mine is the wings of fire series, it is a “kids” novel (think like warrior cats age range)
But Tui T sutherland is so good at writing characters and introducing and describing worlds and characters that i reread it every so often. Like, she managed to write a book from the pov of a mind reader and it works.
Every book is from a different character’s pov and each character feels wholly unique.
The main issue with the series is that the plot is kinda average at best, the characters really carry the story.
“Night Soldiers” by Allan Furst. After his younger brother is killed by a fascist mob, a Bulgarian fisherman is recruited to join Russian intelligence. Trained as a spy in Moscow, he begins to question his trainers and their motives. After being sent to fight in the Spanish Civil War, he makes his way to Paris.
Great book. Reads like Franz Kafka and Ian Fleming decided to collaborate.
