The Commitment

Unbroken: Heavenly Rising #4

by Shayla Black, Jenna Jacob

One Bride. Two Bachelors. Total Commitment?

Seth Cooper must decide between growing a future with Heavenly Young and Kenneth “Beck” Beckman or losing them forever. His heart says yes...but his head knows that if he has to mourn his loved ones again, he won't survive. He chooses Heavenly and Beck—swallowing the quiet terror that their commitment might be the thing that shatters them all.

Then, Seth’s devoutly Catholic mother’s wedding compels the trio to New York. To preserve her happy day, he asks Heavenly to pose as his fiancée, while reducing Beck to platonic friend. The charade is temporary…but it quickly tears them apart.

When the trio’s plans for the future become terrifyingly real, a new discovery forces Seth to confront an old threat—exposing a betrayal he never saw coming and dragging them into the very risk he feared most. With everyone he loves—along with his secrets—in jeopardy, Seth must stop the killer or history will repeat itself in blood. Because surviving the danger is only possible if they fight for it together.

5 Stars are not enough for this EPIC long awaited ending for Beck, Seth and Heavenly. While I expected the wonderfully written sex scenes that both Shayla Black and Jenna Jacobs are known for, what I was not ready for was the highly emotional roller coaster that the triad had to go through to finally get their HEA. Between Seth's tumultuous past, surprises that come out of no where and an ending that had me on the edge of my seat I could not put this down and once I was done I needed to re-read it to make sure I did not miss anything. This is one of those books that I would love to see on the big screen. I am just so sad that the legacy has come to an end. Phenomenal!!

I have waited for years for this final chapter in the Heavenly Rising series. First, you NEED to read the first three books in this series or you will be totally and completely LOST!! The journey that Beck, Seth and Heavenly have gone through is long, complicated and harrowing! Secrets pop up and things get very, very tense. Add some family drama to the mix and you have three people who struggle to keep their relationship going! I laughed, I cried, I cussed and then did it all over again! This series is one of my favorite series of all times!

End of a series is always bittersweet when it's a series that you love and so that's this one for me. To watch Beck, Seth, and Heavenly and all the trials that they go through to finally, finally find their Happy ending/beginning. This series gave me all the thrills and spice that I expect from Black and Jacobs and I honestly can't wait for the next book that they work together on. You've just got to get this!

I have waited YEARS for this book and it didn’t disappoint! Not going to lie, it started off slow for me. But by chapter 9 - plot twist and the book really picked up momentum. I enjoyed how the storyline continued and wove in pieces from the previous two books. Only down side for me was the ending…. Not sure if that means there will be another one!?
