Thunder

"With each passing day, Thunder finds himself increasingly drawn to Makenna despite her mountain of responsibilities and his distrust of relationships. Even crazier is how some of her siblings are working their way under his skin and into his heart, as is Makenna. Just as Thunder starts thinking about dates and promises, the CDMC roars back into his life. They’re responsible for his beloved club brother’s death, and he wants nothing more than to make them suffer. When the threats start coming, and Makenna finds herself caught in the crossfire, Thunder will discover exactly the kind of man he is, and how far he’s willing to go to keep Makenna and her siblings in his life." -- Amazon.com
