Apocalyptic Story Title Ideas? Thanks?!

So I'm writing a story, and the main protagonists are a boy named Avery Banks and a girl named Hayden Florence. A horrible disease takes over the world's females only, much like Toxic Shock Syndrome, but once they have the symptoms of the disease, they only have minutes until they die. So Hayden is immune, along with less than one percent of the world's rapidly decreasing female population, and gets sent to an experimentation lab, breaks out, and finds Avery. Together, with a couple of side characters that will be introduced later in the story, they are on the run, trying to protect Hayden from the doctors and scientists from shock therapy, surgeries, and, finally, death, so they can donate her organs to researching the disease in hopes for a cure.

So, I thought it was a unique story line, and I was hoping for some title ideas for this story? I am totally stuck. Thanks for all of the answers!
