"As in the other books, there's a tremendous sense of adventure here--excellent fight scenes, ramped up tensions, well-drawn characters (new heroes and villains alike), and of course, the breaking of the #1 rule of time travel--no romance!" Lisa Fox, award-winning author of Core Truths. "The only thing regret is that I hadn't read the previous three books--not because I was lost since she does a great job of catching us up on previous events, but because it was That Good. What. A. Ride." Laurie, author on Goodreads "The impressive writing skills that Paulene exhibits has the reader in total infatuation with the characters, total immersion into the story, and makes anyone who finishes her novels beg for more." Mr Tim Kreher, author Look for the plainest treasure in the box, the one with no shine. And there be...the key. With another player entering the world of time travel, the quest is on. Whoever finds the aqua pearl will control the timeline. 17yo Madison and Riley are, once again, forced to launch into the past to try to fix the future. Press-ganged onto a pirate crew, with navy ships in pursuit, they struggle to keep their footing as they navigate to a mysterious island that appears and disappears with the tides. Forming an allegiance with the swashbuckling pirate captain would appear to be the best course. But can he be trusted or will he steal the treasure and Maddy's heart as well? Some sharks operate in the sea, others on deck in this exciting time travel adventure on the high seas. A high-stakes, fast-paced time travel adventure in the golden age of pirates.
