I really liked this book, it felt like revisiting old friends as it's set in the same world as the Study series. Opal is a very likable main characters and I just LOVE the whole idea of Stormdancers, can you imagine someone standing on the beach in the midst of an enormous angry storm, harvesting its power in a tiny glass orb? For me it creates visions of the sea slamming on the rocks, lightning flashing over the water and in the middle one handsome man in a bubble of calm. Who wouldn't fall in love with that?
