Munch Mancini is trying to get clean and get her act together, but when she becomes the prime suspect in a murder case, sobriety may be what gets her killed. A former junkie-turned-auto mechanic, Miranda “Munch” Mancini just wants to make an honest living. But nothing in life is easy, and Munch’s hopes for a new life are dashed when her abusive father turns up murdered, and Munch is the main suspect. Staying clean is one thing, but staying off Detective Mace St. John’s radar, especially when a series of gruesome murders all point to Munch as the culprit, may prove impossible. Her only hope is to cut a deal with the detective, putting her own life on the line to catch a killer. But trust doesn’t come easily for ex-junkies, or for cops. The impulse to betray this precarious alliance may be too strong for either to resist - and may get both of them killed.
