Igneous. When Cooper’s parents divorce, he finds himself landed in Week About—one week with his mum and one week with his dad. Only, it’s not just his dad he has to live with. There’s Lila, too: The other woman, the one who stole the rock-solid foundation of his life. And then . . . There’s Jace. Lila’s son. Lila’s smug, regurgitated-fish-scale-blue eyed son. All Cooper wants is to have his family back the way it once was, but there’s something about this boy that promises things will never be the same again. Sedimentary. Resisting the realities of his new life, Cooper and Jace get off to a rocky start. But rocky start or not, after hundreds of shared memories together, they forge something new. A close . . . friendship. Because friendship is all they can have. Although it’s not like they are real brothers. Technically, they’re not even stepbrothers . . . Metamorphic. But how does that friendship evolve under the pressures of life? Under pressures of the heart?
