The Secrets of Her Past (Harlequin Superromance Book 1909)

An irresistible attraction! 

Veterinarian Madison Monroe faces her days by ignoring her past. That's impossible when her former brother-in-law Adam Drake appears. She'd love to refuse his demands for help—who needs his attitude? But she owes the family. So fine, she'll work at their vet clinic, then walk away. 

Easier said than done. Being with Adam shows the differences between the twin brothers. Intense and intriguing Adam makes her feel things she never felt before. Worse, Adam gets past her defenses, putting her carefully hidden secrets in jeopardy. And once the truth comes to light, everything will change!
