Hot Firefighter
The fourth book in the series, this one features Jack O'Malley, who is a firefighter.
He is investigating serial arson fires. The woman he falls in love with is a former firefighter who is now hearing-impaired.
He must protect her and stop the arsonist. His spiritual struggles relate to understanding who Jesus is.
Firefighters are always good leading men, and Jack is a good guy. This book also introduces Captain Cole Parker, who will show up again in the next book.
