Hit man Gustavo Toro left behind a cryptic treasure hunt for the FBI to follow in the case of his death. Toro's video message sends Agent Dani Vega and her colleagues around the country to uncover his secrets.  Unfortunately, they are not the only ones following the clues - someone else is reaching their contacts before Dani can get the answers they need. Can they reconstruct Toro's past and find the messages he left for them before they become the targets themselves?

----------------------------------

I found this book stood okay as a stand-alone for the plot, but there were gaps in building out the characters. Reading book 1 first, which also featured Toro, might have helped fill in the character for me. Same for understanding Wu & Vega's interactions.

I appreciated the author's thoroughness throughout the book - the descriptions and details for agency-specific procedures truly immersed me in their world. Reading the Author bio afterwards confirmed that the author has experience with law enforcement and is writing about areas she has experience. 

Thank you to Netgalley and Thomas & Mercer for the ARC for this early review.
