On a beautiful day in June, the ground broke open.

In Japan, you're always prepared for an earthquake. That's why Kai knows just what to do when the first rumbles shake the earth. But he does the exact opposite of what you're supposed to do: He runs. And then the tsunami hits.

Meanwhile, on the other side of the Pacific, Kai's cousin Jet sets sail off the coast of Astoria, Oregon. She knows she should have checked the tide--she always checks the tide. Except this time she didn't.

When the biggest mistakes of their lives bring them together, Jet and Kai spend the summer regretting that one moment when they made the wrong decision. But there's something about friendship that heals all wounds, and together, Jet and Kai find the one thing they never thought they'd have again--hope.
