Uncharted by L. T. Ryan and Gregory Scott is Book 3 in The Blake Brier Series.
A heinous discovery by kids spending the day on a boat is the first of several horrific events happening in this coastal town. When Blake receives an unexpected call from an FBI Agent regarding a dire situation with an old friend he never thought would want to see him again, he agrees to assist in any way he can. He informs the woman (Haeli) with whom he's getting serious about the limited information he has and takes off to find out how he can help.
Upon arrival, he's surprised to find it's his former late lover's sister whose daughter Lucy has gone missing. The two women who are the young girl's moms are frantic with her disappearance fearing she's run away with a no-good kid she'd been seeing. Mending the past is foremost for the woman who appreciates he's come so far to help them find Lucy.
The facts are slim until connections begin to form, but it's slow-going as to who's involved in what eventually looks more like kidnappings than those of runaways.
Uncharted is at times a gruesome story - definitely not for all readers. Although well-written and inclusive of small hints as to who the evil antagonist is, those hints prove illusive until very close to the end. I will say there were a few things that didn't work for me, but overall it's an interesting story with plenty of drama and tension - a satisfactory ending, but not without certain sorrows.
Due to an unforeseen outcome from his trip, Blake faces a new challenge when returning home.
Father, please continue to bless L. T. and Gregory with the skills you've given them to create stories. May they know from whom those abilities come. Thank you for them. In the Name of Jesus, Amen.
