Kate and Gillian are stepsiblings, each bearing two generations’ worth of mental illness and cruelty.
One is an obsessive-compulsive baker, the other an oversexed hyper-intellectual. Emotionally stunted adults, they live separate, brittle lives.
But they converge when Jonah, Gillian’s beloved brother and a murder suspect, introduces himself to Kate.
As Jonah continues his unannounced visits, and a string of murders plagues the county, Kate can’t seem to stop wondering which sibling her mother loved most.
