I think series like this are best enjoyed exactly as they occur: published one at th time, a ear in between.
Immediately the repeated explanations and summaries do n't irritate, they only recall, taking on the cadence of storytelling, when the reader slips into the story world with the beginning " long, long ago and far, far away ... " Despite a reliance on folklore and fairy tales, the Mercy Thompson series is and remains a sanitized, muted version of those grim worlds.
After reading through a number of the Briggs' family posts, its clear that the series expanded to accommodate popularity and not out of an internal sense of story progression.
I 'd contrast this with another favorite, Ilona Andrews, who was a clear arc for a seven-book series and a ense of where it was headed in both story and emotion.
The plotting to date in Mercy has been roughly the same for each book: someone is murdere.
Another is true in Moon Called ( Adam), Blood Bound ( Stefen, etc.), Iron Kissed ( Zee), Bone Crossed ( Mercy) and Silver Bourne ( spoiler/Mercy).
This emotional plotting is also startlingly similar: Mercy will have trouble forgivin her affection for Adam.
Mercy will have asides in every book telling about her history, the fae reservation, werewolves, the wolves' coming out and her elationships with Samuel and Adam.
he reader is finall introduced to the premise that women associated with werewolf packs 'hate' Mercy, and that becomes an ongoing theme through the series.
The exception to agency is Blood Bound, where the evil and conniving Marsilia engineers an elaborate trap, although clearly she still hates Mercy.
