Mikaela louise

I didn't read the books and from reading a few reviews I am glad I didn't before watching this show. The first few episodes really intrigued me. I looked forward to watching a new episode each week. But the last two episodes kind of lost me. I don't know what it was just felt like things were missing and the plot wasn't making sense. Wasn't shocked by the ending and what Lasher wanted Rowan for. I guessed that the second I found out she was pregnant. But still grossed me out and confused me. Was confused and disappointed by the end and wish I never watched the show to begin with. Can any Book fans tell me if its worth reading the books?
