Jeffery Deaver is probably my favourite author, overall.
South Of Nowhere (2025) is 5th in the Colter Shaw series.
BUT … this book is not nearly one of my favourites. I found it too slow.
BUT I quite appreciate the mantras that run through Colter’s head, which he picked up from his survivalist father.
In the TV adaptation — Tracker — Justin Hartley plays Colter Shaw. A good pick.

When a levee collapses in Hinowah, a small town in Northern California, Colter Shaw is brought on by his sister, Dorion, a disaster response specialist, to help locate a family swept away by the raging water, with mere hours to survive.
But after a surprise attack along the river obstructs Colter’s urgent search, the siblings are forced to consider a new reality: Is the levee at risk of failing from natural causes, or is someone sabotaging it? Colter and Dorion must race against a ticking clock to uncover the truth and save the citizens before the village washes out completely, destroying everything and everyone in its path.
