Thorndike Press large print core series.

Carrie Hanwell is a female firefighter in Texas, and she's a total pro at handling other people's emergencies. But when her ailing mother asks her move to Boston, Cassie suddenly has an emergency of her own. She finds a job at a tough, old-school Boston firehouse, but firemen aren't exactly thrilled to have a "lady" on the crew--except for the infatuation-inspiring rookie. But she can't think about that, because love is girly, and it's not her thing. And her old captain had advised her never to date firefighters. Cassie can feel her resolve slipping, and it means risking it all--the only job she's ever loved, and the hero she's worked like hell to become
