The Alice Network by Kate Quinn. However, one of our mystery group members, Gayle, has a blog too, It's a Mystery! She wrote a great post about it, so, I'm going to send you there. Here's the link to her thoughts on this book and our meeting.
Gayle is such a great member of our group. She always makes a list and spreadsheet when we have our 'best of the year' meeting and also when we read for a theme or 'award winning/nominated' books. Plus, she subs for me when I have to be out if she can. She's practically perfect!! Take a look at her blog and what she shares. She loves the new mystery movies that have been made from successful cozies and writes about them. She also is in contact with several authors that might not be familiar to you. It's a Mystery! is a blog that I can recommend!
As to what I thought about The Alice Network, I enjoyed it very much. I want to read more books this year with these 'unknown' stories about women's contributions to war efforts. And, yes, this one is based on real people and real situations. Kate Quinn has new book coming out soon and I'll be talking about that on Wednesday.
