Rereading the Series having read Book 4.
This is a wonderful series of books following a single story line: the growth and development of Emily and Justin. What comes fuller into focus in this installment is Emily's drive to overcome a serious obsession.
Along the way, Emily and Justin explore their complimentary kinks and the sex in this book ramps up. In addition, Emily is not on any contraceptives yet wants to enjoy unprotected sex, both with her husband and others. Emily and Justin enjoy the quest for their first child, and while Justin is away for more than 3 months straight on an oil platform, Emily enjoys an unprotected romp. When Justin gets home, he isn't 100% certain whether the child is his, feeding his kink.
This book, like the rest of this series, is carefully crafted and nuanced. If you're racing through, looking for the sex scenes, you will miss the subtlety of this series. I gather a number of people have speculated on the fathership of the baby. If you pay close attention, I believe that question is clearly answered (I'm waiting on the Book 4 Epilogue to settle the question, but my thoughts are clear).
Through this series, we really see the growth in Emily. There is a background character that intimidates her. In this installment, we see Emily gaining the upper hand. It's delightful to see her being firm in the face of an unsettling character.
While the sex in this book is excellent, and you really feel for the characters, the key to this series is the character development, and caring and growth of this deeply bonding/bonded couple. If your focus is one sex scene after another, this is probably not the book for you.
If you have the time, savour this book; I'm sure you will enjoy it.
In addition to this book, there is a Epilogue to Book 3 available from the authors. It's another well written piece. In this Epilogue, Emily recognizes and accepts her husband and herself for the people they are, kinks and all. This Epilogue also sets the stage for Book 4. Reading it will enhance your understanding of the journey this loving couple is on.
