From the author of the acclaimed If You Go Down to the Woods (HarperCollins) comes a new thriller in the slipstream of Jacob’s The Monkey’s Paw and King’s Pet Sematary.

Joe Jimenez, grieving father and estranged husband, on the eve of the anniversary of his son's death is on the brink of complete despair when he witnesses the arrival of a strange atmospheric anomaly. The rift – a curious tear in the very air of his backyard – appears nightly, and after some experimentation, Joe discovers that for everything that's sent through the rift, something similar, but horribly wrong, comes back. And when something on the other side claims to be in possession of his son, Joe has to make the most important decision of his life: should he go through and find out?
