Skeleton Key Book Series One Skeleton Key. Endless Adventures. https://skeletonkeybookseries.com Caroline Abernathy has lost her mind. Perhaps it was the bump on the head she took when an afternoon sailing expedition cruised right in the middle of a violent storm or maybe the stress of grad school has finally proven to be too much. Whatever the cause, she finds herself alone in a strange underwater world and at the mercy of a ruthless pirate. Everyone has a price, at least according to the Pirate Prince, Ezra Castle. In order to purchase the fare needed to bring her home, Caroline agrees to spend the remainder of the voyage on his ship, helping him locate the priceless artifact she cost him. What starts as a simple journey turns deadly when their ship is attacked by a band of assassins. Stranded, wounded, and without transportation, Caroline and Ezra will have to rely on each other to make it back alive. Life and love are on the line and time is running out. Tick Tock.
