Trial by Fire (Newpointe 911 #4)
Terri Blackstock

Paramedic Issie Mattreaux is no icon of virtue, but she cares enough about her teenage nephew, Jake, to track him down when he turns up missing. Only, what she finds is far more than a harmless bonfire on the outskirts of town.
After a chilling attempt on Issie's life, Nick takes on the role of protector even as he struggles wit the tragedy that has struck his church. Whoever is behind the fire is far from finished. Unknown to Nick, that person's twisted agenda now threatens to consume everything he loves most.
