Apocalypse is a young adult novel written by British author Tim Bowler.

The book deals with teenage Kit trying to find his parents after a storm blows them onto an island in which the local community is hostile and a mysterious man who resembles him in every detail (with the exception of age) in a series of events that turn his world upside down.

[1] The book begins with a group of people (later revealed to be ancestors of the Skaerlanders) attacking a mysterious man on a rock.

The story then moves into the present, with a family of three on board a yacht on a sailing voyage.

The protagonist, Kit, and his parents, Jim and Sarah Warren, are taking a final voyage on their yacht, the Windflower.

Once a wealthy family, Kit's father has recently declared bankruptcy, and their yacht will have to be sold when they return.

During which time, Kit picks a small carved boat out of the water and glimpses a man who resembles him in every single way, except age.

They run aground on a mysterious island and find it difficult to get their yacht back to sea.

Kit goes exploring and sees the man he saw at sea again, as well as a young girl about his age, who quickly disappears.

He tells them that they have 24 hours of safety, so the family leaves the village and quickly go back to their vessel.

Kit attacks them and manages to free the girl, who runs away and jumps off a nearby cliff.

Kit returns to his yacht and discovers that the tent is slashed open and his mother and father are both missing.

However, he is attacked and chased by the angry Islanders, whose attention is briefly diverted by the same man.

Ula explains to Kit that the Islanders are a religious community who believe themselves to be Torchbearers to God and that they will be saved from the Devil.

He leaves the cave and goes round to the back of the island, where he sees the man building a cairn and is forced to help.

Ula manages to get him to the safety of a cave by the time he regains consciousness four days later.

When Ula asks when her father died, Torin responds "Even as you watch," and throws himself to his death.

School Library Journal said the novel is "beautifully written and its themes are intriguing", although they also said that "[t]he unsettling climax may disappoint some readers who prefer rational endings".
