Surviving Hell by Aurelia Skye

Sofia survived the hemorrhagic version of the HLV virus, and then she survived more than a year as a prisoner at Fort Glacier, where she was subject to experimentation to learn the secret of her recovery. When she finally escapes, she’s determined to survive the collapse of society and being on her own again.

Finding the residents of Camp Utopia aids in survival, and Ben, the handsome leader, gives her a reason to live, not just survive. So does the new addition, Joshua, and she finds herself gravitating toward both of them. Their triad is soon tested, first by betrayal and then by danger. Sofia wants to survive when Fort Glacier comes looking for her, not willing to let a possible cure escape them, but what will it cost her, her lovers, and the people at Camp Utopia?
