If V. C. Andrews and Kate Morton had a literary love child, Emma Rous' The Au Pair would be it.

Seraphine Mayes and her twin brother, Danny, were born in the middle of summer at their family's estate on the Norfolk coast. Within hours of their birth, their mother threw herself from the cliffs, the au pair fled, and the village thrilled with whispers of dark cloaks, changelings, and the aloof couple who drew a young nanny into their inner circle.

Now an adult, Seraphine mourns the recent death of her father. While going through his belongings, she uncovers a family photograph that raises dangerous questions. It was taken on the day the twins were born, and in the photo, their mother, surrounded by her husband and her young son, is smiling serenely and holding just one baby.
 

I usually write my own plot summaries, but no matter how hard I tried, I couldn't come up with one as succinct but evocative as the one that appears on The Au Pair's back cover.  The professionally-written copy captures the book perfectly. 

You know I love me a psychological thriller, especially one with Gothic vibes that hints at dark family secrets coming to light, so this one definitely appealed to me from the moment I heard about it.  And you know what?  It delivered.  With an intriguing premise, complex characters, and a tautly-plotted storyline, the novel kept me riveted throughout.  Although I saw some of the twists coming, I didn't figure everything out until the very end.  Even if The Au Pair gets a little predictable, it's still an engrossing read that I could not put down.  This is Rous' first novel and I cannot wait to see what she does next!
