A woman goes missing during a crowded festival, apparently abandoning her young baby. One year later her body hasn't been recovered, and the appeal for information is being renewed at the opening day of the same annual festival by her daughter, partner and ex-partner. Aaron Falk is there to attend a baptism, and soon finds himself caught up in the tragedy and the heartache left behind, and tracing the outlines of her mysterious disappearance. 

A well developed story that unfolds naturally with well-developed characters and tangled familial relationships. The final revelations are chilling but satisfying and the whole thing is extremely effective.
