He knows what she carries.
He knows how to make her let it go.
And he may be the most dangerous person she’s ever trusted.
When Sam arrives in a small Irish town, she is looking to find peace with her past. Instead, she finds Callen. Quiet. Protective. Impossible to read. He sees things in her that no one else does. He knows when she is lying, when she is afraid, and - most dangerously - what she needs to hear. For the first time in her life, Sam feels understood without having to explain herself. Through Callen, she discovers the Threshold, a strange place where language disappears and buried memories can be shared. There she begins to realise that the secrets surrounding him are connected to something much darker. As she gets closer to the truth, she must decide whether the man who understands her best is actually helping her... Or quietly deciding who she is allowed to become.
Sometimes being understood is not the same as being safe.
