Sirens & Scoundrels - Tales from the Quaquaverse, #2

This sexy, screwball tale of mayhem and lust on the high seas is yet another decidedly adult tale, set in a rollicking pirate adventure genre with an enemies-to-lovers plot. The dread pirate Knox kidnaps Duke Argo's daughter, Ravenna, and demands all the Duke's treasure as ransom. Argo charges his daughter's fiancee - the Royal Navy Captain Ozymandias - to save his daughter and to destroy the pirate once and for all.
His reward will be Ravenna's hand and half the dukedom. In a fierce sea battle, both the pirate and the captain lose their ships, and are marooned with only a few men on opposite sides of an island ruled by the monstrous lizard-man Kalakuta. Captain Oz, as he is known to his men, must  find the "Noxious" pirate Knox to free his love, but the journey is rife with dangers both deadly and arousing, and the horrific monster pursues them relentlessly, killing the crew off one by one. It doesn't help that the captain is a supercilious fop who hates to get his hands dirty, and the pirate is a dashing, sexy hunk of a man who captures the young lady's fancy.
Throw in a a pair of twin, talking monkeys and a mermaid who seduces the captain and is now with child, or fish, or whatever, and you have a swashbuckling, fantasy romp that alternately tickles the funny bone and the libido. Will Oz save his future wife, defeat the beast, and capture Knox? If he does, how will they make it back home with no ship?
