Jack Harper is back to fight the cult she thought she destroyed. With more violence, drugs and underage drinking than even Pivot. Perish had great world building which led to an enjoyable read. Perish has given me new hope for the series. I enjoyed the twists this installment had and the storyline really caught my attention during the second half of the book. Now, I am anticipating the final book of this trilogy to see where Jack goes from here!
