Time of My Life by Cecelia Ahern

Lucy Silchester has an appointment with her life – and she’s going to have to keep it.
Lying on Lucy Silchester’s carpet one day when she returns from work is a gold envelope. Inside is an invitation – to a meeting with Life. Her life. It turns out she’s been ignoring it and it needs to meet with her face to face.
It sounds peculiar, but Lucy’s read about this in a magazine. Anyway, she can’t make the date: she’s much too busy despising her job, skipping out on her friends and avoiding her family.
But Lucy’s life isn’t what it seems. Some of the choices she’s made – and stories she’s told – aren’t what they seem either. From the moment she meets the man who introduces himself as her life, her stubborn half-truths are going to be revealed in all their glory – unless Lucy learns to tell the truth about what really matters to her.
