Fiction by Terri Blackstock.
Good thriller by a Christian author. I always recommend Terri Blackstock for an exciting read.
I mean, I was so interested in this book that I barely noticed the garage took an hour and a half to give me an estimate on my brake replacement.
This is number three in a series, though, so you have to read Intervention and Vicious Cycle first.
Don't worry, they're all major page-turners.
And, Terri Blackstock is popular enough that most libraries stock her. So not a huge monetary investment.
