A Day Late (Foothills #3)
Carrie Thorne

Claire Dabney is done with her veterinary medicine program and is finally going to Foothills with her boyfriend, Ryder Mallory, to "meet the parents." Turns out, when you're both working your butts off and never see each other, you may not have noticed that you haven't had a meal together in weeks, forgot the other's birthday, and haven't had sex in months.
Stuck in a pretentious mansion with a snooty mother-in-law and a man you don't like as well as you thought... and finding out the love of your life isn't the guy you came with, but his brother? Worst and best vacation ever.
