This book was a fun, interesting, tough read. I loved the plot and the characters and their relationships. The going back and forth in time took me out of the story a few times, but the bits in the past definitely helped understand how their characters were built. It was also very interesting how they all had different views on maternity and parenthood and I loved the ending that leaves the very main plot point in the air. 
Would love it if there was more to read on those three.
