#106 Symbiont by Mira Grant

The second book has Sal constantly on the run while she is the one person everyone wants so they can figure her out and what makes her so special. Sal on the other hand is also finding out things that make her different from other hosts that have had their symbiont take over. This story does introduce more people like Sal to her and the reader.  The only problem I had with it is that it is a middle book to a trilogy so there isn’t any clear wins and a definite cliffhanger ending.
