No good deed goes unpunished.

When an unwanted Valentine's Day present is dumped at the shelter, volunteer Lily decides to foster the poor dog herself. A little attention is all he needs to blossom into a loving pet, ready for his forever home. Plus, helping a poor, rejected animal will distract her from her own problems. Win, win. Right? Wrong. Valentine needs more than a makeover if he's going to be adopted. He destroys her home, hates to be groomed and when he behaves better for a perfect stranger than he does her, Lily swallows her pride and begs the good looking but quiet stranger for help.

After losing his canine partner in a horrific moment that upended his future, sexy and stoic Shane turns to books, walks in the park, and remodeling his grandmother's home. No more intense K9 officer career, no more dogs, no more risks. But it's hard to ignore the misunderstood mutt at the park and his well-intentioned, but clueless, handler. Shane reluctantly agrees to give her a few tips and tricks, but that's all. He won't care. He won't get invested. And once Valentine finds his new home, his life can go back to normal.

But Shane doesn't bargain on a new normal in town and, suddenly, Valentine's Day will never be the same.
