He Promised to Protect Her—But the Truth Could Destroy Them Both
Sienna Cross has loved Kane “Riot” Mercer for almost her entire life.
He was the wounded boy she protected beneath the Iron Saints clubhouse, the best friend who became her first love, and the man who promised that no one would ever hurt her while he was alive.
Years later, Kane is the powerful vice president of the Iron Saints MC, and Sienna is the woman everyone believes he worships.
Their marriage looks unbreakable.
It isn’t.
While Sienna endures painful fertility treatments and quietly fights for the future they planned together, Kane begins spending more nights away from home. He blames club business. She blames stress.
Then she finds a hidden phone.
One message changes everything.
The other woman is not a stranger. She is part of the club. Someone Sienna trusted. Someone who listened to her fears, comforted her through heartbreak, and smiled in her face while sharing her husband’s bed.
But Kane’s affair is only the first betrayal.
When Sienna discovers how many members of the Iron Saints knew the truth and protected Kane’s position instead of protecting her, she refuses to beg for loyalty that should have been freely given.
She removes her ring.
Burns the vest bearing his name.
And walks away from the husband and family who believed she would always forgive them.
Eighteen months later, Sienna has rebuilt her life far from Saint’s Hollow. Kane has lost his wife, his rank, and the man he once believed himself to be.
He wants a chance to apologise.
Sienna knows apologies are easy.
Living with consequences is harder.
Then a hidden ledger belonging to her late father exposes secrets buried inside the Iron Saints—missing money, illegal weapons, and a murder someone is still willing to kill to conceal.
Now Sienna is in danger.
And the only man ruthless enough to protect her is the same man who broke her heart.
Forced back into Kane’s world, Sienna must decide whether the man who betrayed her can ever become someone she trusts again.
But Kane is hiding one final truth.
And this time, discovering it could cost Sienna more than her heart.
The Promise He Broke is an emotionally intense motorcycle-club second-chance romance filled with cheating, betrayal, broken vows, club secrets, forced proximity, danger, deep grovel, and an earned redemption that does not come easily.
