Cactus Creek Challenge [EPUB ebook] 

Anything he can do, I can do better. At least that was what Cassie Bucknell thought before she pinned on Ben Wilder’s badge and took to patrolling the streets of Cactus Creek, Texas. Cassie has been in love with Ben since primer school, but Ben treats her like a little sister. When they are picked to swap jobs for a month as part of the annual Cactus Creek Challenge in their Texas hometown, the schoolhouse is thrown into an uproar, the jail becomes a temporary bank vault, and Cassie and Ben square off in a battle of wills that becomes a battle for their hearts.
