 Mercury Striking is the first in a new post apocalyptic series. In a world ravaged by a bacteria that will either kill patients or leave them with the possibility of turning into a sociopath, humanity struggles to survive. This has a rich back story, revealed throughout the book as Lynne fights to find the rumored lab and remember research that was lost to her. Part medical thriller, part zombie apocalypse, part romance, there is never a dull moment here. 
 Lynne Harmony has a target on her back, or literally in her heart. Her glowing heart is a beacon to her identity and the source of the stigma surrounding her. I loved her conviction and strength, her caring and her determination. Though she often has challenges beyond the rest of humanity, she knows what she needs to do and does her best to not let anything get in her way. 
 Jax Mercury is the leader of a large surviving community, almost begrudgingly. He knows how to lead soldiers, but doesn't know how to connect to the people. His goals are to keep his people alive and healthy, and avenge his brother's death. 
 When Lynne seeks out Jax's help, she knows there is danger in revealing herself. But she never expected more than a small amount of protection and some help locating labs. These two were an interesting pair. Both so focused on their own troubles, they haven't stopped long enough to notice anyone else until they are forced to when Lynne arrives at the compound. The surprise as their simple arrangement develops into more is uncharacteristic for both of them. 
 This is a great group of characters. From the soldiers, to those keeping the community strong, there are so many characters that have intriguing stories, secrets, and tales to tell. My favorite side character, the one that I was anticipating a story focused on him not long after meeting him, sadly won't be getting his own. But the character that will get the next book is intriguing, mysterious, and definitely knows more than he is letting on. 
 This was one of those books where the main storyline almost didn't need a romance aspect. I like having the romance for my own entertainment, but the story is rich and full even without the connection between the two main characters. It's the kind of story that will continue to keep me engrossed even after the main couple is no longer the focus, simply because of the overarching conflict.
