Firestorm is book 6 in the Refuge series by Lisa Tawn Bergren, but you will enjoy this one whether you've read the others or not.
The book is characterized as "Christian Fiction" but isn't as cheesy as some others in this genre that I have read. Reyne and Logan are fire-jumpers. After a bad experience with a jump, Reyne distances herself from the front lines. Then she meets Logan, another jumper. Reyne then finds herself dealing with the question of whether she wants to "jump" back into the fire - figuratively and literally. :) It was an enjoyable, easy read.
