Dead Caller from Chicago A Mystery

the long version

Bad things are surfacing in Rivertown, in a huge hole in a block of bungalows; in the river, where the dam trapped what should never have been in the water. And from the past, where secrets long buried have risen again, to kill. Then comes a phone call from a dead man, and the sudden disappearance of almost everyone Dek ever held close. A trail leads north, to the end of Michigan, past the chop of the angry waters beyond, to an ice swept island most everyone wants to forget. But there are no answers there, just more questions, and another dead man pointing straight back to Rivertown, to the hole, and the dam, and secrets that want to keep killing.
