The first book in this set, The Amish Girl, was good. Some grammatical errors but the plot held together and kept me interested. The second book, Sins of the Father, was less so. More characters introduced. Sadly, from there, third - Blood Brothers and fourth - Bless the Child, became ... Well, I'll just call it weird.
I do not think these four novellas were properly planned -- just written. So many characters it was hard to keep them straight. An idea introduced and not really fulfilled.
I recommend the first novella, The Amish Girl. Maybe the second. Can't recommend novellas three & four.
