"I had a large family: my parents and five other siblings. I'm the youngest and Hendrickson's the oldest – there's almost fifteen years between us. Eight years ago, on the eve of my sixteenth birthday, my father came down with the virus..."

As a family of mostly adult werewolves who have left their childhood home, it's been almost a decade since all the Lockwoods went on holiday together. Amelia is the youngest, and with her sixteenth birthday around the corner and her eldest brother visiting after years studying medicine abroad, the ideal time for that family vacation presents itself.

An idyllic cottage in Wales should have been the perfect setting, but small disturbances can be hard to see, and by the time their father's infection of lupine distemper is revealed, it's far too late for any of them to avoid the repercussions.

Isolated and fearful, Hendrickson and Amelia desperately try to nurse every family member that falls ill, but they're fighting the virus themselves ... the first fatality strikes. And there's a full moon coming, twisting the path of recovery.

Pain heightens; boundaries fray; breaking point is reached. Survival is going to cost the siblings their future.

Taking place eight years before the Eye of the Storm series and told through Amelia's voice, we learn of the thirteen days that altered her and her brother's lives forever.

*Since the Eye of the Storm events have not yet taken place, you do not have to read that series before this book. 13 Days can be read as an unrelated standalone.
