Last Chances — M.A. Grant

When Catherine Jacobs's parents died while she was in high school, her brother's best friend Dallas Miller was there to help pick up the pieces. Several years and her looming college graduation later, Cat's motorcycle-riding knight in tattoos is about to ride off into the sunset to start his own life. Now she only has six days to convince him to fulfill her secret fantasy of having him for her first before he's gone forever. Dallas Miller shouldn't have listened to Cat's proposition. He can't forget her request, no matter how much he needs to. Losing his best friend's trust would be bad enough, but Cat's the only woman he's ever dreamed of sharing a future with. It's already breaking his heart to leave her behind; he can't bear giving her what she wants and becoming her biggest regret after. Once Cat knows Dallas is interested, she's determined to see her plan through. Sure, there's a lot to lose if she messes this up, but the promise of a happy ending—and a happily ever after with the perfect man—are worth the risk.
