I read the blurb on the inside cover of the book and was like, "This sounds like a really good time"! Then, I realize that it's the same author as the Veronica Speedwell series, and I'm like "Point #2, check"! 

This book is just OK to me. Didn't hate it, didn't love it. 

Things I loved:
1. A group of badass, elderly ladies who were assassins.
2. The chemistry-banter between said ladies.
3. Female rage, oh female rage. 
4. Someone is after them now that they've retired and they're hear to fuck shit up. 

Things I didn't love:
1. The need to suspend disbelief.
2. The fact that everything these ladies set out to do just comes super easily.
1. & 2. are things that in other books, such as Stephanie Plum or Finlay Donovan, I have no problem with - I even enjoy it. But for some reason to me, I just didn't like it in this story as I just feel it didn't fit the narrative. I mean, I know there were the best at their job but...like they just always knew exactly what to do and even when they ran into a sticky situation they just walked away unscathed...that doesn't even happen in the silliest of books I've read. 
3. There is not major conflict - or if there was I missed it. 

So, ultimately: this isn't a book I'm necessarily going to be shoving down people's throats - but if you're look for a light, funny, book about some badass elderly assassins, maybe this is it for you.
