Troika weaves the stories of Perla, Julian and Sophie. It's intense, and you'll want to keep reading to find out what is going to happen.
Perla is a strong character despite her occupation. She knows people must look down on her, but she keeps her head held high, and has rules in place so she doesn't let her emotions get involved. Julian had a harsh past that he tries to overcome and constantly deal with. Sophie is a character that is hard to like at times because of her situation. It's easy to empathize with her, but some of the choices she makes are frustrating.
The writing in Troika is beautiful. The words are woven together with precision, and you can tell when each character is telling their story. You visit past events that show how each person came to be how they are.
Sorry this is kind of vague. I don't want to give away too much because it would definitely be spoilery. But this is a story about finding yourself and love in unimaginable circumstances.
