Shattered Hearts by Kenna Shaw Reed

Nina’s world stopped at the same time as her daughter’s heart.
Now, blocking every emotion is the only way she can survive.
Derek believes he must be strong, not just for himself, but for Nina, too.
Now the small fractures in their marriage – once healed by love and friendship – threaten to tear them apart.
Desperate to bring Nina out of her grief, Derek turns to the last person he would have expected to seek out: the man who almost stole her away from him.
