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.

But how does that friendship evolve under the pressures of life? Under pressures of the heart?
