The Amish Firefighter's Widow — Samantha Price

When Amish woman Katie's volunteer firefighter husband dies while in the line of duty, she is heartbroken. Not only have her two young sons lost their father, but the child she is carrying will never know him.
Her husband's best friend, Mark, steps in to take care of Katie and her children. Many months pass and Mark is offered an opportunity away from Lancaster County.
Not wanting to leave Katie and the children behind, he makes his feelings known. Katie tells Mark she would never marry again, and if she did, it would never be to another firefighter. Katie urges him to take the job.
Months turn into years before Katie realizes that she has made a terrible mistake.
When Mark finally returns, will Katie find that she's left things too late?
