Evergreen (Japantown Mystery #2) by Naomi Hirahara; 2024. Softcover.

It's been two years since Aki Ito and her family were released from Manzanar detention center and resettled in Chicago with other Japanese Americans. Now the Itos have finally been allowed to return home to California - but nothing is as they left it. The entire Japanese American community is starting from scratch, with thousands of people living in dismal refugee camps while they struggle to find new houses and jobs in over-crowded Los Angeles. Aki is working as a nurse's aide at the Japanese Hospital in Boyle Heights when an elderly Issei man is admitted with suspicious injuries. When she seeks out his son, she is shocked to recognize her husband's best friend, Babe Watanabe. Could Babe be guilty of elder abuse? Only a few days later, Little Tokyo is rocked by a murder at the low-income hotel where the Watanabes have been staying. When the cops start sniffing around Aki's home, she begins to worry that the violence tearing through her community might threaten her family. What secrets have the Watanabes been hiding, and can Aki protect her husband from getting tangled up in a murder investigation?
