Number 19 is Mad Kestrel by Misty Massey. Basically, all I can say about this one is it has pirates, main character is female pirate captain, there's magic, and main character (Kestrel) has pre-requisite "I'm attracted to you but I hate you, I hate you, I don't trust you, I have to trust you, I hate you still, ok, you're trustworthy, I love you" relationship with other character who is sort of one of the main protagonists. Not a great book, but fun enough. I like pirates.
