It's WWII, and we meet Will who is working on the Manhattan Project and Maggie, his sister who finally got a job.

Things were going well for the brother and sister team until they found Ruby hiding and frozen under their back porch.

They don't know what to make of Ruby...she has bruises, seems helpless, kills bugs, and knows a lot about poisons.

They also find a vial with poison in her pocket, learn that she tried to kill her fiancee, and her mother asked Will to keep her hidden.

What is going on? Could Ruby be a spy? Did Maggie hear her speaking German?

You will not know what to make of Ruby either or in fact any of the characters.

THE HALF-LIFE OF RUBY FIELDING has great characters, great writing, an interesting story line, and lot of secrets and surprises.

If you are a fan of historical fiction and mystery, you should enjoy this twisty read. 4/5

This book was given to me by the publisher via NetGalley for an honest review.
