One of my new favourite books this summer is called Red Notice. Based on a real story, the protagonist started his career at a Wall Street banker and later decided to invest in Russia where he made his money. Along the way, he exposes certain corruption in Russia which led to him and his colleagues escaping the country for their lives. One of his friends wasn't so lucky and ended up in jail and tortured to death. This is a story of high finance, murder and later becoming an activist to overcome the corruption in Russia. Definitely one of my new favourite thrillers
