Follow me into the dark

the long version

"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."--
