Celia lives a quiet life with her books, parents and younger sister Poppy. Her stifling normality comes crashing down when Poppy introduces her to Alister Tyler, a boy so beautiful that it hurts to look at him. Alister turns her world upside down and right way up all during the few weeks of winter break. She falls for him as a snowflake would fall in a snowstorm, fast, wildly and dangerously. Alister is the type of boy you should stay away from, but just want to know. All of a sudden, Alister disappears, and Celia feels as if she is falling all over again, only this time not for a boy, this time she is falling into an empty abyss of questioning, lies and shady business.
