This is How You Lose the Time War by Amal El-Mohtar and Max Gladstone is a book that I would definitely recommend. I recently read it and was blown away by how new and different the storyline was. Two agents, Red and Blue, become intertwined despite working at rival organizations, and their high-stakes relationship spans decades and literal strands of time. It is a fast-paced read that immediately grabs your attention and does not let go. I've never read anything like it. I very much recommend this brilliantly written novel.
