Flawed (The Billion Heirs) by Vanessa Vale, Helen Hardt

The bad boy brother. The by-the-books detective. A random meeting that will change their lives.

Miles Bridger would rather be home in New York than stuck on a Montana ranch with his newfound half brothers, thanks to his deadbeat dad's will. Miles now works with bulls and hay bales instead of custom bikes. He keeps his sense of humor about the whole thing...until a dead body surfaces on the ranch and he and his brothers are thrown headfirst into a murder investigation.

Sadie Hopkins plays by the rules in her job as detective, so she's only too happy to turn a little naughty during a bachelorette party dare. Heat flares between Sadie and the gorgeous blond man she approaches, but when a high-profile case crosses her desk the next day, she's in for a surprise. The man from the bar is none other than Miles Bridger...and he's a murder suspect.

Despite this revelation, Miles and Sadie's chemistry sizzles. But the flawed Miles doesn't do relationships, and Sadie's past crashes into the present with a surprising discovery that could spell danger for both of them.
