On an island, somewhere out in the vast ocean, Cee has only one goal: find her sister Kasey. In Joan He’s enthralling, futuristic page-turner, the relationship between two sisters holds the destiny of earth in the balance. As climate change finally ravages our land and oceans, a chosen few take refuge in a levitating city built in the sky. The rest of humanity flounders on the surface, victims of extreme weather and a polluted atmosphere. Kasey may be a teenager, but her intellect leads her to a plan that will allow earth to recover and humans to thrive once again. But first she must solve the mystery of her missing sister, whose love of the ocean and swimming might have cost her life. Kasey’s search leads her to a mysterious boy named Actinium, who is either trying his best to help her or might be her biggest enemy. In a twisty, unpredictable way that’s reminiscent of We Were Liars, nothing is as it seems in this unforgettable book.
