What would it take to destroy your closest friendship?

Alison and Ciara meet at college in Dublin and soon become firm allies, sharing a flat and facing the world together. Ciara is all that Alison aspires to be - sassy, confident and fearless. Although their backgrounds could not be more different, they find solace and humour in each other's company.

That is until gorgeous Dan Abernethy, a young medical student, enters their lives, and everything changes irrevocably. Love turns Alison's world upside down and a terrible betrayal threatens everything she holds dear. It is only when tragedy strikes many years later that Alison and Ciara are offered a chance at redemption.
