Erin wants a fresh start. With her thirtieth birthday coming up, she's taken a long hard look at her life (the job she hates, the wedding she just cancelled) and concluded that it's basically a mess.

If only she knew where to begin. A trip to her hometown in Ireland to visit her beloved grandmother is a welcome escape from her disappointments. But, there, Erin also finds an unexpected solution to her problems, in the form of a magical family heirloom.

No more of the 'what ifs' she's been tormenting herself with -- now all she needs to do is whisper two little words and she'll be able to see for herself what might have been, had she chosen a different path. But as Erin gets caught up in one 'if only' after another, changing her life proves more complicated than expected.

And she starts to realise that, by chasing dreams and searching for an easy fix, she might be missing out on what's right in front of her...
