Eastern Tide (The Aldabreshin Compass Book 4) by Juliet E McKenna

Chazen Kheda has returned to the Archipelago from the western Isle where his actions had freed the savages from the rule of the cruel wizards and dragons. Unfortunately the some of those dragons have fled to the Archipelago, as it was his actions that unleashed these dragons on the inhabitants Kheda decides to hunt them down and remove them. Aided by Risala, Velindra and a new wizard Sirince he must remove the dragons with out the Warlords finding out that he is using magic, which would mean instant death.

This was a fantastic book I could not put it down and was left desperate for more at the end. My one problem was that Kheda seemed to whinge a bit too much but it did not detract from the story at all.
