The Eternal Return of Clara Hart by Louise Finch
Spence and Anthony have been friends for years, but it’s only when he witnesses a classmate die in what looks like a tragic accident at a house party that a flicker in the fabric of time helps Spence ‘see’ Anthony for the first time.
When Spence wakes up to the same day again and sees Clara, the girl who died, alive and well, it’s clear he’s been granted a second chance. And a third. And a fourth…
Caught in a loop, condemned to experience the same 24 hours over and over, Spence tries to prevent the terrible events of the party.
To break the spell he has to re-evaluate everything he previously took for granted and find the courage to call out his own and others complicity in events that marked the life and death of Clara Hart.-Goodreads
