Wild Night - Wilder Irish, #10

This is definitely love. Now all he has to do is convince her. Confirmed bachelor Colm is living the good life with a thriving law practice and all the freedom the playboy has come to enjoy. Until a city-wide blackout and the greatest sex he's ever had has him reconsidering his single status. Unfortunately, he doesn't realize the woman of his dreams is actually his lifelong frenemy, Kelli. After a few too many drinks at a Halloween party, Kelli spends the night in the arms of a man who rocks her world.
However, when she learns her mystery Mr. Right is Mr. Hell No, Colm Collins, she's ready to run for the hills. But Colm refuses to accept just one wild night with her. He wants them all and the sexy man plays dirty.
