As many people have said, this book satisfies on every level. The plot? Crackingly suspenseful and believable. The young daughters of a single mum go missing from a K-Mart car park and tracking down what happened to them takes us down various interesting rabbit holes. The characters? Superbly well presented with deft economic touches that enable us to appreciate exactly what they’re like in all their subtlety, both the deadbeat junkies and the various others, both good and weirdly bad. Successful bounty hunter Alice Vega flies in from California at the request of the girls’ great aunt. She’s a tough loner, but she asks for the help of Max Caplan, ex-cop, now a PI after taking the fall for a colleague. Their relationship is initially antsy, but as the tough days roll on, they develop an intuitive understanding and respect that foreshadows a possible romance. A particular joy is Cap’s 16 yo daughter Nell: a smart, brave and sensible girl who makes sure he eats and with whom he discusses cases like an adult. The police are struggling with budget cuts and that curse of our era, the opiate epidemic. Cap’s old boss disses his offer of help but is hauled over the coals for it in a terrific scene. Vega has access to an invaluable source of help: a hacker who is not bound by the laws of evidence the cops and the FBI are under. Luna is a terrific writer whose prose never falters. May her next book be soon.
