I haven’t read the sequel so I can’t specifically recommend it, but this book in itself was great and definitely stands in its own. A great action packed story for fans of sirens or pirates! Some romance too but not the main focus, and non-spicy.
To Kill a Kingdom (Hundred Kingdoms, #1) by Alexandra Christo
This book tells of a beautiful romance between a man paralyzed in an accident, and the woman who becomes his caretaker. It’s actually a part of a series but I’ve only read this one so I’m putting it here.
