Morgan Carter, owner of the Odds and Ends bookstore in
Door County, Wisconsin, has a hobby. When she’s not
tending the store, she’s hunting
cryptids—creatures whose existence is rumored, but
never proven to be real. It’s a hobby that cost her
parents their lives, but one she’ll never give up
on.
So when a number of bodies turn
up on the shores of Lake Michigan with injuries that look
like bites from a giant unknown animal, police chief Jon
Flanders turns to Morgan for help. A skeptic at heart,
Morgan can’t turn down the opportunity to find proof
of an entity whose existence she can’t definitively
rule out. She and her beloved rescue dog, Newt, journey to
the Death's Door strait to hunt for a homicidal monster in
the lake—but if they’re not careful, they just
might be its next victims.
