One Moonlit Night by Gaelen Foley
I received this book in exchange for an honest review. Gable is a rake with no plans to marry soon. Katrina is well above marrying age with no prospects. They meet in the park where she is lamenting the fact that yet another suitor chose somebody else instead of her, and he is looking for an earring that came off the lady he was with earlier that day. Gable ends up convincing her that being a spinster can be okay. They become friends and when Gable is told by his father that he is to wed within four weeks or be cut off, he thinks that marrying his friend is the perfect answer. Only Trinny now considers herself off the market. Gable decides to try convince her that a marriage between them is in his, and her, best interest. It's a sweet, funny and engaging story which I highly recommend. And I can't wait to read the next book in this series.
