I am about to start writing the Sixth Voyage in the series: Gallows Wake, although I have recently brought out a short novella prequel When The Mermaid Sings, which, technically, comes at the start of the adventures, although I would recommend begining with Sea Witch.
The Place : The Pirate Round - from the South African Coast to the sun drenched Islands of the Caribbean.
Escaping the bullying of his elder half brother, from the age of fifteen Jesamiah Acorne has been a pirate with only two loves - his ship and his freedom. But his life is to change when he and his crewmates unsuccessfully attack a merchant ship off the coast of South Africa.
He is to meet Tiola Oldstagh an insignificant girl, or so he assumes - until she rescues him from a vicious attack, and almost certain death, by pirate hunters. And then he discovers what she really is; a healer, a midwife - and a white witch. Her name, an anagram of "all that is good." Tiola and Jesamiah become lovers, but the wealthy Stefan van Overstratten, a Cape Town Dutchman, also wants Tiola as his wife and Jesamiah's jealous brother, Phillipe Mereno, is determined to seek revenge for resentments of the past, a stolen ship and the insult of being cuckolded in his own home.
When the call of the sea and an opportunity to commandeer a beautiful ship - the Sea Witch - is put in Jesamiah's path he must make a choice between his life as a pirate or his love for Tiola. He wants both, but Mereno and van Overstratten want him dead.
