Private investigator Margo Angelhart has recently rejoined her family’s PI business, but she never forgot the reason she walked away. Three and a half years ago, her father, Dr. Cooper Angelhart, pled guilty to killing his colleague. While she never believed he was guilty, her mother, Ava, refused to help investigate and wouldn’t explain why.
When a nurse who once worked with Cooper reaches out, Margo leaps at what could be a potential lead…only to stumble across the nurse’s grisly murder. Then, Cooper is mysteriously transferred to a penitentiary out of state in the middle of the night, and Ava finally discloses why her husband confessed to a murder he didn’t commit.
Now the entire Angelhart family must fight to clear Cooper’s name. But every step they take drags them deeper into a deadly conspiracy…and into the crosshairs of some very powerful people with fortunes on the line. They’ve killed to keep their secrets before. And this time, the target is an Angelhart.
Highly addictive from start to finish! The Angelhearts have been doing a fine job of wrapping themselves around reader’s hearts, so getting to the center of what really happened with dad Cooper all those years ago is really rewarding. This book is filled with heart, redemption and so much mystery. I love that Margo stood tall in her faith about her dad, and seeing her finally get some answers just feels right. The family as a whole is great and I know there is so much more to build on for them all and hope we will continue to join them as one mystery after another comes into their lives as their family settles back into a peace they’ve been greatly missing. Well developed characters, a fairly good follow through of keeping a reader up to date on past happenings even if they are starting with this book in the series and great chemistry as they right wrongs.
I highly recommend this book as well as the rest in the series to anyone who enjoys a tight knit family of investigators who have had their share of ups and downs in life and with each other but always stand behind one another when the going gets tough. Great intrigue and relationships.
