ONE PROMISE Aged thirteen, best friends Eleanor and Fin are inseparable. Convinced it will always be this way they make a pact - to go to university together, always live near each other, and if they're both single at 35 they'll get married. TWO DECADES Eleanor and Fin haven't spoken in fifteen years. Life has run away from them and they're both far from where they'd dreamt of being all those years ago. CAN THEY STILL KEEP THEIR WORD? It takes tragic circumstances for Fin to come back into Eleanor's life, but everything has changed since the last time they met. Is it too late to mend their friendship? Or is there a chance they can keep some of the promises they made?
