Survivors by Anna Hackett

In the aftermath of a deadly alien invasion, a band of survivors fights on…

Nate – Long before the aliens invaded, former Marine Nate Caldwell came home a broken man. Going off-grid in a cabin he inherited in Australia’s Blue Mountains, he survived the invasion with only his dog Blue for company. For two years, he’s avoided the aliens and any survivors – he’s done his fighting and can’t go into battle again. But when a young woman crashes into his lonely existence, with the aliens hot on her heels, she changes everything…
Dak – Captain Dak Vaughn only has room for his job as head of security for Groom Lake Base. His focus has to be on keeping all the survivors alive, and not on the tough, attractive new recruit who gets under his skin. But when a dangerous mission requires them to go deep into alien territory, Dak finds himself up close and personal with a woman who is pure temptation.
Alexander – Marine engineer turned base leader, Alexander Erickson, leads a tiny base of survivors in the snowy climes of Norway. Balancing the needs and safety of his group keeps him busy, and he longs for someone to share the load, someone to call his own. The one independent woman he wants refuses to see him as anything more than a leader and a younger man. But when mysterious alien activity encroaches on their safety, they will join forces to investigate and Alexander might finally have his chance.
