A family reels from the effects of WWII nuclear fallout, but this is far from the Japan of 1945. It's 2006 in Washington State, and the war just took another life. In this new release of WWII home-front historical fiction, a 12-year-old boy named Asher seems to make his dad furious no matter what he does. In hopes of getting his dad back to normal, whatever that is, he looks for a way to fix it all. But he soon finds that he’s bitten off more than he can chew, when he discovers clues suggesting his grandpa’s death may not have been as natural as he was led to believe. The secrets he uncovers might change everything, but what does a nuclear bomb from 60 years ago have to do with his grandpa and does it have something to do with why his dad hates the world? Asher, Mari, and their quirky little sisters team up to solve the mystery before Asher’s dad destroys the family. It doesn’t take long, though, for Asher to realize that trying to save someone else from their own despondency can end up putting your own health at risk. Through the support of Mari and their top secret spy sisters, Asher uncovers enraging revelations about his grandfather's death, but realizes, a little too late, that some mysteries are better left unsolved.
