Chasing Fire - Nora Roberts

Little else in life is as dangerous as fire jumping. Flying past towering pillars of smoke, parachuting down to the edge of an all-consuming blaze, shoveling and sawing for hours upon hours, days at a time, all to hold the line and push back against the raw power of Mother Nature.
But there's also little else as thrilling - at least to Rowan Tripp. The Missoula smoke jumpers are one of the most exclusive fire-fighting squads in the nation, and the job is in Rowan's blood: her father is a legend in the field. She's been fighting fires since her eighteenth birthday. At this point, returning to the wilds of Montana for the season feels like coming home - even with reminders of the partner she lost last season still lingering in the air.
