The Matchmakers Mission Book 6 (en Inglés) - Lacey Davis

Bad Boy Angel Meets Matchmaking Witch 

At Cauldron Academy, Rose learned the hard truths about being a white magic witch. Now in the real world, she is to carry on the family matchmaking business even though she doesn't believe love lasts. With the final battle looming, she's devoted to preparing, but she doesn't realize she's closed herself off from the strongest power in existence to fight evil.

Cade Vonner is a die-hard playboy turned angel after crashing his Corvette into a tree. His heavenly task is to fight in the battle against the devil and to help Rose learn that not only is love the most powerful human emotion, but the very thing that will keep the world from slipping into darkness. But how can he teach something he has no experience in? 

Before they can save the world, he must gain her trust and show her he's the man to help her on the quest to close the gates of Hell. Will the love between them be enough to save the world from the hundred-year curse?
