Leviathan

We will survive this, Caroline. When a stranger arrives in their village and asks to see the damaged bay, Caroline Daniels and Joanna Chase know that word of the creature has spread despite the efforts of Mr. Smith. With tensions simmering between France and England, they depart in haste for Medby, where Sir Edward's brother resides. There they hope to discover if Thomas Masterson has stepped into Sir Edward's shoes, and now wields the monster called Leviathan.
The situation in Medby, however, is far worse than they anticipated. Claiming the French attacked his ships, the younger Masterson seems about to launch an audacious reply. But his true plans are not so straightforward, and there is little time for Caroline and Jo to uncover them. With the threat of war demanding risks in kind, Caroline and Jo must weigh their deepening affection against the greater good .
and learn to trust not only their instincts, but their hearts as well.
