Returning to Love - Amanda Kabak

Six years after finding each other, Charlie and Elizabeth have been married for two years, but all is not wedded bliss between them. Charlie has transformed herself into an in-demand trainer and nutritionist, offering a mind-body-belly approach to personal improvement. Eager to prove herself to Elizabeth—and everyone else for that matter—Charlie has packed her schedule with clients and is gone much more than she's home. And she's committed to do even more.

Elizabeth's best friend declares that this is karma rearing its head since Elizabeth had previously made an art form out of letting her job consume her. But she'd found a way to reinvent herself and slow down, prioritizing Charlie while still running her tech consulting business, The McIntyre Group. But now she's frustrated at Charlie's schedule, her absence even when she's sitting right next to Elizabeth, her attention buried in her tablet, her clients' well being more important than their marriage.

When Charlie's depression creeps up on her, she's intent on muscling through it, keeping her struggles to herself while Elizabeth is trying to manage trouble at her growing firm. As Charlie descends deeper, refusing to ask for help or slow down, Elizabeth finds distraction in Renee, a mentee whose insistent flattery and compelling intellect lures Elizabeth farther away from Charlie. With secrets and broken trust straining their marriage, will they figure out a way to come back to each other or will their relationship splinter under the pressure?

The hardest promises to keep are the ones made after happily ever after.
