Deadly by Julie Chibbaro can be found on Link+.  After reading an article about strong female lead characters in an article by Joanna H. Kraus in the San Jose Mercury News, I became interested in reading the titles she recommended.  Of course, this was after reading the Hunger Games by Suzanne Collins.  I was interested in reading other young adult titles with strong female protagonists like Katniss Everdeen.

Prudence is a young lady who is much more interested in learning about science in the male-dominated early 1900's.  She applies as an assistant to an epidemiologist, Mr. Soper.  Soon, Prudence finds herself involved in finding the cause of several typhoid epidemics around the city. 

This tale is a fictional account of what happened to Typhoid Mary.  Mary Mallon was the first person who was identified as a healthy carrier of the typhoid disease.  It was unheard of at that time for a healthy person to spread disease.  Trying to convince the public, the courts, and Mary Mallon becomes an uphill struggle. 

Julie Chibbaro is also the author of Redemption, also a Link+ book.
