This book is an immediate sequel to Lyons' previous book featuring FBI Agent Caitlyn Tierney, 'Blind Faith', as Tierney is recovering from the events at the end of that book to open this one. Otherwise, no other characters from 'Blind Faith' make an appearance here, and Lyons only revels minor spoilers from that book, so you could theoretically read them out of order.
Tierney is recovering from surgery and trying to figure out where she fits in at the FBI when she gets a call from a prisoner asking to investigate the disappearance of his daughter. Not necessarily an FBI matter, however Tierney is well acquainted with this prisoner, who was her father's best friend until he confessed to killing a Cherokee tribe elder near their small hometown, which eventually led to Sean Tierney's suicide, as he was the police officer who had to arrest and charge his friend with murder. Still bitter after 26 years, Caitlyn is unsure she wants to help Eli, but remembers his daughters and the friendship she had with his older daughter, while the younger one, Lena, who is now missing, was merely a baby at the time of the murder, which was the last time Caitlyn saw any of them.
Upon venturing back to her hometown, Caitlyn is introduced to the resident motorcycle gang, the Reapers, who nearly kill her the moment she flashes Lena's photo to the leaders, asking if any of them have seen her. She knows right away there is something fishy, but can't figure out what a bunch of bikers would have against a college student, who according to her father and her roommate, was in town researching her family's history and later the court rulings related to the Native American population in the are. Also, she is reunited with her mother, who nags her about retiring from the FBI for something safer and can't figure out why she would want to come back to such bad memories, and her uncle, who served in somewhat of a fatherly role to her after her own father's death and is now operating a huge casino, just outside Indian territory.
Lyons also gives readers a second perspective by showing right away that Lena is still alive but is being held captive, so interwoven with Caitlyn's search for her is Lena's own struggle to figure out where she is and why in the world someone has her hidden.
Overall, the storyline was good, and I didn't see most of the twists and turns coming, definitely a series I'd like to see continued on. It did get a bit predictable at times and isn't a literary masterpiece, but it made a perfect book to read late at night during dinner breaks at work. I still like Lyons' Angels of Mercy series best, but since she brought that one to a close, I'll take this one. Seems she has a lot of series, so I always have to look inside the cover to figure out if a book belongs with another I already read or is the start of something new.
