Evergreen: The Complete Series by Cassia Leo

Laurel and Jack’s marriage was a fairy tale.
Jack and I had everything. Then, in one brutal instant, the universe tilted on its side, discarding us into black nothingness.
Now, I have a cocky jerk for a husband. The only way we communicate anymore is in the bedroom.
With nothing left to lose, I write Jack a goodbye letter and head for Portland, where I quickly meet a neighbor who helps me find a job.
My new neighbor—hot, tattooed ex-soldier Isaac Evans—is complicated. Nevertheless, we form a fast friendship, bonding over our mutual desire to create something beautiful from the wreckage of our lives.
But despite the distance between us, Jack and I are still trying to make things work—fighting and playing dirtier than ever. And he doesn’t appreciate my new friendship with Isaac. Not one damn bit.
