Isabella, the Captain of the Wanderlust Tides longs for adventure in the seas. During her journey of embarking on a cruise with her friends, she makes a decision that changes her life forever. After stopping in Nassau, she comes across the poster of a wanted pirate, the ruthless Dominic Spade. Unbeknownst to her, he and his crew hijack Isabella’s yacht and forces them all to join him on a treasure hunt to claim the signet ring that would win him back his megayacht, the Ruthless Marauder. Isabella fights her growing feelings for Dominic, but the more she gets to know him the more she finds he isn’t what he seems. She didn’t expect her past to come to light when she runs into an old flame, the King of Spear Grove, who has been hunting Dominic for his devious crimes. Isabella doesn’t know which is deadlier––confronting the demons of her nightmares, falling in love with a wanted pirate, or the Leviathan that waits for them to claim the treasure at the Sea Chapel of Brazil.
