The story was a bit too slow for me, expecially at the beginning, but despite that it was very interesting and I'm looking foward to the next volume. 
 Sally Mitchell had an miraculous recovery from a car accident seven years agoin witch she lost all her memory. Sally's medical bills are paid by Simbogen, a corporation that created genetically enginered parasites that helps human's health, and as a new mistery sickness starts tp spread she finds herself in the middle of things. She is a nice main character and I loved Tansy and her crazyness altough she is only introduced later on.
