I've come to the understanding that I'm a total sucker for stories where the rake/rogue falls in love with the heroine AND her adorable children (or in this case, young siblings). Georgette Heyer's Frederica is a classic example.
In The Accidental Wedding, Anne Gracie takes a familiar scenario -- handsome injured stranger with amnesia nursed by poor but proud and of course beautiful young woman in a cottage leading to a marriage of convenience -- and creates a whole new story. All of the characters, but especially the hero, are charming, even the old dragon great aunt. Nothing is entirely predictable, except the guaranteed HEA.
A delightful read.
