I loved this book. Lydia is an amazing, complicated, difficult, unbearably endearing and heart-tugging heroine. Her determination and anger and genuine desire for mathematical correctness (literally, she's a mathematician, which, o/) were amazing. And Will's corrosive shame for a terrible mistake in his past was delineated SO precisely and perfectly. I teared up MANY times reading this, and WOW does Cecilia Grant have a way with a sex scene. Incredibly hot and incredibly intense and emotional. Plus I love a good gambling plotline! I cannot recommend this book enough.
