Daniel Healy has been dead for two years, and his parents are still in the process of healing both themselves and their relationship. When Alexander Healy suggests that it's finally time for his daughter-in-law to accompany them on their periodic fishing trip to White Otter Lake, it seems like the perfect opportunity for the four surviving members of the family to become reacquainted with one another. Fran is dubious at first, not really understanding what a fishing trip could do for them as a family.

That was before she knew about the monsters in White Otter Lake, of course. The monsters change everything.

Before long, the entire Healy clan is embroiled in a fight for the lives of the creatures that live in White Otter Lake, which may be the last of their kind in the world. If they want to save these majestic plesiosaurs, the family will need to find a way to come together in order to solve the mystery of what the guardian of White Otter Lake has disappeared to.

It's bullets versus brains as the Healys finally step up to do their jobs, and preserve the crytozoological world. No matter what it takes.
