Up in Flames Series by Em Petrova

East Street Fire Company is battling dangerous fires all over the city thanks to an arsonist on the loose. Between a new recruit and several veteran firefighters, they’re on red alert for the criminal. Faced with unseen dangers and even explosions in their own back yard is bad enough but time is running out for their condemned firehouse. Good thing the women who fall into their arms—and laps—are good at handling all that testosterone and distracting them from their stressful duties.
