Hoping the twist/solution is different than what I am guessing. This book is okay but the relationship between the FMC & her husband feels very…plastic. I’m confused by some of her choices, especially telling her husband she’ll wait to tell him about something at a specific restaurant when they go in a couple of days instead of telling him about it that night in bed when he asked/in the morning. It’s weird.
