I absolutely love Ali Hazelwood. She has great characters, funny and smart dialogue, and I enjoy the science-y plot lines. This book looks like another winner, love the chess vibe and now I’m invested and want to know what happened to Mallory’s dad, what the prior relationship with Nolan was, and more about the Defne Bubikoglu character-what a great name! And I love all the diversity in the characters. A main female character who’s an auto mechanic-genius!
