Protecting Chaos by Kate Allenton

Soulmates of the heart. Strangers by choice.
They were destined to be together. It was smarter to stay apart.
She’s his best friend’s sister and a forbidden temptation.
His family secrets might destroy her future and dreams.
At least that’s what Ashton Bennett believed when he walked out of Stella Michaels’ life to work for the FBI. A badge proves handy to protect the ones he loves and keeps his secrets from being exposed. His life is far from perfect without Stella Michaels to share it, but it’s the one he chose years ago.
Stella Michaels is on the verge of having it all. She has the house, the friends, and a successful painting career. Her life is headed in the right direction, until health issues and a home break-in cause her brother to intervene. He sends the one man back into her life that is capable of destroying her heart again.
With Stella the target of a deadly threat and her life on the line, Ashton must fight the heat raging between them if he has any chance of saving her life.
