With the rest of her life in a mess, Iris struggles to make sense of her murky family history, until a chance meeting with Guy Wilder changes everything. Son of the local criminal matriarch Guy has plenty of problems of his own, but there's something about Iris that makes him more than willing to help her search for the truth.
