When Juni Jessup and her sisters Tansy and Maggie put all their beans in one basket to open Sip & Spin Records, a record-slash-coffee shop in Cedar River, Texas, they knew there could be some scratches on the track, but no one was expecting to find a body deader than disco in the supply closet.

Family is everything to the Jessups, so when their uncle is arrested by Juni's heartbreaking ex on suspicion of murder, the sisters don't skip a beat putting Sip & Spin up for bail collateral. But their tune changes abruptly when Uncle Calvin disappears, leaving them in a grind. With their uncle's freedom and the future of their small business on the line, it's up to Juni and her sisters to get in the groove and figure out whodunit before the killer's trail--and the coffee--goes cold.

Music and mocha seem like a blend that should be "Knockin' On Heaven's Door," but caught up in a murder investigation with her family and their life savings on the line, Juni wonders if she might be on the "Highway to Hell" instead.
