Lucy Young may only be twenty-four, but she's already exhausted. She's tired of dating, tired of being on the bottom rung at work, of having no money and living off super noodles and Rice Krispies. She wants to know who she's going spend her life with, to have a successful career, and just once, to get out of her overdraft. She's ready to skip to the good part.

But you should be careful what you wish for . . .

Because when Lucy wakes up in a strange bed with a strange man, she finds that somehow the impossible has happened: her life has jumped forward eighteen years and overnight she has everything she thought she wanted. But is Lucy really ready for this level of responsibility? Is her new, grown-up life as sorted as it seems? And most importantly, what happened in the years she missed, and will she ever get them back?
