What happens when you’re wrongly accused of something terrible, and you lose your job? If you’re Molly Fraser, you pick yourself up and one way or another get yourself into the biggest effort of the present day—Florence Nightingale’s mission to the Crimea.

But life is never smooth for the young parlormaid. In addition to the hardships she faces trying to care for wounded and dying soldiers in rat-infested hospital facilities, she must sort out the truth of her own heart. Is her friend from service the man she should choose? Steadfast, loyal, loving? Or should she choose the young doctor with a mysterious past?

Find out when the book comes out on April 12.

In the meantime, here are some historic pictures of Florence Nightingale and the conditions in the Crimea.
