Yesteryear is an unhinged and gripping read, unlike anything I have read before. The narrator is both unlikeable and unreliable, which makes the story even more intriguing, as you never quite know what to believe. The timeline is not always clear, which can be confusing at times, but it also enhances the overall sense of confusion and chaos throughout the book. What I found most interesting were the very current topics, particularly social media, how fake it can be, and what really goes on behind the scenes. Definitely a book that gives you plenty to think about!
