Uncovering the family tree spells trouble for Jennie McGrady.

Jennie McGrady is on the vacation of a lifetime—an extended trip to Ireland with Gram. And when the opportunity to stay in a castle arises, Jennie is ecstatic. For some reason, though, Gram doesn't share Jennie's enthusiasm. Then, just before their plane lands, Jennie discovers a threatening note: If you value your life, stay out of Ireland.

Helen Bradley is returning to Ireland to settle the estate of her mother—a task she's still not ready for.
