First, about the books..
The women in the stories are primarily portrayed as independent man haters until they're not. It's very confusing. They also tend to jump to conclusions and dramatically overreact to situations unless their lives are in danger. When their lives are threatened, they are surprisingly calm. Many of them claim to hate drama but then bring all the drama to the story.
There were many times throughout the books I was thinking this could be a paranormal romance. All of the men are super strong and fast, unbelievably handsome, incredibly wealthy, can smell when a woman is aroused, and the children have superpowers as well. The way the children are portrayed actually drives me crazy. They are all far too advanced/ mature for their supposed ages. A baby less than 6 months old already talking? An under two year old who speaks in complete sentences, understands the concept of Santa and how it relates to Christmas and presents (asking to have her younger brother traded for a new one), and can verbally manipulate everyone around her. A 7 - or 8 year old who gives relationship advice to adults and understands the complexities of all the interactions between the adults around him. Then, in the last book, the hours old infant who winks at the adults "knowingly" and laughs hysterically at jokes told by his brother, these are not believable characteristics for children.
Second, about the narration...
I cringed every time the female narrator (Morae Brehon) took over. She is terrible at accents, of which there are several in the book, including Southern, Russian, Swedish, & and Irish, to name a few. She also tends to drop the consonant at the end of many words, especially ones that end in "d." Her normal speaking voice is quite pleasant. If she didn't attempt the accents, it would have been better. I think the flow of the book would have been better overall if they used just one narrator, and I preferred the male (Sean Crisden).
Additionally, there are so many words that are misused in this book, but it's hard to say whether that's on the narrators or the author. If you made it this far and still want to read this book, don't say I didn't warn you.
