Fifty Fifty by Steve Cavanagh is a case of good sister vs evil sister. When the story opens up, two frantic phone calls are made to 911, each call claiming the other sister murdered their father. You can feel the adrenaline even through the writing. Defense lawyer, Eddie Flynn, is back, and he has taken on the case of one of the sisters, Sofia. The other defense lawyer is Kate, who has taken on the case of the other sister, Alexandria. Because both sisters were at the crime scene with DNA pointing at both of them, they are tried together, and the prosecution makes sure there won’t be two separate trials. They don’t care which sister did it; they just want the guaranteed conviction.  

But what’s the motive in killing their father? He is worth millions being the ex-mayor of NYC and was in the process of changing his will. So which sister did it? I thought I knew, but this book left me with my jaw open.

The narration is through all four characters, but also SHE, which is the sister who is the guilty one. We quickly realize that we have a serial killer on our hands, and she has no remorse. The characters are well developed, giving us background on their upbringing and the aftermath of some incidents that make you realize why this sister would have some psychological problems affecting her as she grew up. 

If you are someone who loves to watch court tv, documentaries on serial killers, and murder mysteries, then this book is absolutely perfect for you. Even the courtroom scenes have shocking and clever moments from the defense, and you feel like you are sitting in the room watching this all unfold. The SHE character also gets to work on removing witnesses, so you’ll be on a reader rollercoaster navigating the emotions throughout. 

Fifty Fifty is part of the Eddie Flynn series, but you do not need to read them in order.
