Hidden Hero (Ancient Court #3) (The Hidden Saga Book 9‪)‬

The gripping Romantic Fantasy adventure continues... After a year-long separation and a search across continents, Macy and Nic have found each other again. Now they must find her family—the birth mother who abandoned her at the hospital and fled back to her people's secret sanctuary—if they are to beat the clock and save the human race from the onslaught of the coming Plague.

Alessia didn't intend to activate the deadly virus, but after determining that Nic betrayed her, she's almost glad she did. The only problem? She won't be around to enjoy the aftermath—she's being held captive on a remote, windswept island by a mysterious guy who's completely immune to her Sway and won't let her get close enough to use her deadly glamour on him.

 
Give in to the Glamour once more as the end of the human world looms, an ancient secret is unearthed, and a hidden hero emerges!

Author's note-- The Ancient Court trilogy is a subset within the Hidden Saga. It is set in the same world and features many of the characters Hidden fans know and love from the previous books as well as introducing new characters from the mysterious Ancient Court in Europe. If you've read the earlier Hidden Saga books, you'll be entranced by the deepening story. If you haven't, then HIDDEN GAME is the perfect point to jump into the Hidden world, and you won't be lost or confused by the storyline. Then the magic continues in HIDDEN MAGIC, and the subset trilogy wraps up with HIDDEN HERO. Then be sure to read the final book, HIDDEN HEIR, which features all your favorite characters from the Hidden world.
