After Ephraim's mother believes she has identified his body after an accident she attempts suicide and Ephraim finds her slumped at the kitchen table when he gets home from school.
Among the unidentified boys belongings which inadvertently come to Ephraim he finds a strange coin that can grant wishes...except it doesn't grant them in quite the way Ephraim expects. Things go horribly wrong each time he makes a wish, creating strange and frightening experiences and shifts, and affecting and changing his life and also the lives of the people in his world.
Quite an intriguing sci-fi plot with parallel universes and dopplegangers. An interesting take showing how the same person can develop into different personalities given altered circumstances and it's a good point that Ephraim takes responsibility for the actions he takes and does his best to rectify things.
A really good story with realistic teenage characterisation. I like the plot twists and the ending.
One of MacLeod Andrews' strengths is narrating Young Adult novels which he does with sincerity and credibility, always seeming invested in the story and connected to the characters.
