Butterfly Kingdom (Teaser)

~He wanted to know why things did what they did...He was obsessed by the compulsion to know how things worked and why they worked like that. It was as if he could make a little of his own life make sense, by making sense of everything else. Maybe his life was far more complex and confusing than we all realised.~

Fay is sixteen years old.
Her ex-boyfriend, Callum, committed suicide three months ago.
She receives a letter from him, supposedly written before he died. Fay follows the instructions on the letter, but she is led into dark corners she didn't know existed.
On her journey, Fay discovers things about Cal she never knew. Dark things. Things she didn't think were possible in her love.
Will Fay grant Callum his final, dying wish? Or will she turn away and move on, this time for good?
