There's a lot to like about this duology - it's an imaginative, creative world with a lesbian pirate captain! Ladies who kick ass! Sex positivity! And a cool magic system.
Regarding the ending though - I'm fine with the less traditional happily-ever-after, but I wish that it had been more of Ananna's decision. She spent so much of the book with her seemingly unrequited feelings for Naji that I think she should have been the one to realize that she needs to be independent and by the sea, even if Naji can't always be there with her.
