The third book in Emer McLysaght and Sarah Breen's phenomenally successful, No. 1 bestselling Complete Aisling book series.

Aisling's turning 30, and she's still a complete Aisling.

Business is booming at her cafe BallyGoBrunch, her best friend Majella is expecting the hen of the century, while Aisling is in the throes of a fling with the handsome and mannerly blow-in James Matthews. Life is all go.

When the big birthday hits, Aisling is faced with a huge surprise and an unexpected decision.

Throw in a hapless wedding planner, a mysterious American visitor, the return of her brother Paul, not to mention her ex John's face around every corner, and Aisling's got an awful lot on her plate.

When doubts, worries and an unfortunate clash threaten to get the better of her, Aisling needs to dig deep to see if she has enough strength and inspirational quotes to make it through.
