Good Kind of Gone - Hearthstone, #5

Sometimes healing from the past is possible when we find someone we want a future with. Maggie Monroe never imagined she would be breaking into her dead twin brother's apartment the first time she saw Paris. Desperate to feel safe after their tumultuous childhood, Maggie has built a quiet, staid life as a librarian, completely avoiding adventure or romantic entanglements. Keeping their family's dark past a secret wasn't hard when you didn't let anyone in.
Sebastian had been all she had left. Finding the truth of his murder was the only thing that mattered to her. Tanner Stone is his family's dark secret. Though his diabolical biological father, Bruce Tanner, never claimed him, most of Stone's Canadian half-siblings have welcomed the family bastard with open arms. After more than a decade with Australia's Security Intelligence Service, Stone isn't quite sure jumping into the Tanner clan's orbit is such a good idea.
He spent the first half of his life ignoring the fact the man he called dad wasn't his biological one, and the second half unraveling just how dangerous and deep Bruce Tanner's global crimes went. As Maggie and Stone's paths intertwine, they dance around their budding attraction as each must decide who to trust. When a dangerous force threatens the global power scale and their loved ones, Maggie and Stone cautiously team up.
Will they be able to put their distrust aside long enough to avert a global disaster, or will old family feuds destroy all hope, and their chance at love?
