When I saw a book where the queens of crime fiction were playing detectives of their own... I POUNCED.  Though I may only have read Agatha Christie so far, each mystery author / character's voice shone through. Now I'm so curious to read more and compare the styles to see how they match with the way they are described in this book.

I also loved reading a fictional account of the real life Lillian to be fascinating.  I honestly expected more kickback and undermining, especially from the men in this book and it was surprising to see that they actually listened to her (for the most part). 

There were also a lot of very timely themes from history that are unfortunately still relevant (probably unintentional, but still interesting). I had an inkling of what happened but I really enjoyed following along and especially how each mystery author acted as an unobtrusive sleuth in her own way.
This book embodied how creative, smart, and cunning women are, despite how they are/were treated especially at this time. I would LOVE for this to become a series and see more of these collabs.

Note: I listened to the audiobook and it was lovely.

Thanks to the publisher for a free ARC; my thoughts are review are my own.
