Mas Arai, Hiroshima survivor and hard-working California gardener, has never been a warm and fuzzy father. His daughter Mari harbors lots of resentments towards him. She doesn't understand his Japanese reserve. But now she's asked him to visit her in Manhattan. She needs his help with a garden her husband is working on.
In Manhattan Mas meets his infant grandson for the first time, and Lloyd, his tall blonde American son-in-law. He also finds a dead body soon after his arrival, in the garden where he's helping out his gardener son-in-law.
Mas ends up investigating this murder, because the police suspect either Mari or Lloyd of being the killer. In helping his family defend themselves from a murder charge, Mas has a chance to bond with them as never before.
The plot is rather complicated. The writing style is not particularly subtle or sophisticated. But the story is entertaining, and Mas is an interesting character, so I will probably continue off and on with the series.
This is a good book for readers who enjoy feel-good detective stories, and novels about the lives of Asian Americans.
