A spooky dream of a gigantic crow and an old, crumbling church in the lost reaches of a forest. A hint of mystery, murder and mayhem in dark underground passages. A poor magician and his little girl, surrounded and harassed by a group of mad trappers...
These are the visions that bring Ian and Connor to the site of their abandoned tree house where, unsurprisingly, the crow awaits. As they sit in the embrace of the crow's eerie time knot, the strange bird tells them a nearly two-hundred-year-old story of how a town and great church came to be and of the misery that befell it. Of how the church became home to many animals and birds, and of the massive oak that had since grown up through the floor and slowly engulfed the church's remains. But now the tree has begun to wither and an avalanche of death will soon follow. The two boys are the crow's only remaining hope because of an innate talent they have been diligently hiding. They will be required to walk into the teeth of an old crime that has gone years unpaid, and of course the crow cannot promise that they will not be swept up in the flood of danger and madness that is fast approaching. Because something has changed in The Bone Cell and Connor and Ian are the only ones who can do anything about it.
