Whew, just finished my book club's pick, so this is fresh. For me, the whole story hinges on the island-born mother, Covey. Her journey from Jamaica to England and then the States under a changed identity is the spine everything else hangs from. But 'key' characters depends on if you mean central figures or vital catalysts. Covey's estranged adult kids, Benny and Byron, are massive—they're the ones piecing together their mother's recorded past and their own fraught sibling dynamic. And Eleanor, their mother under her new name, whose deathbed confession kicks it all off. You can't forget Charles Mitch, the abusive man she fled, or Bunny, her childhood friend who sees everything. Honestly, the cake itself feels like a character in how it ties the generations.
Sometimes a minor character like Lin, Benny's ex, reveals more about Benny's struggle with intimacy than pages of her own narration could. And Gibbs, the lawyer holding Eleanor's secrets, acts as a quiet guide. It’s less a story with a clear hero and villain, more a tapestry of lives altered by one woman's decision to run. I kept thinking about how characters who never meet—like Covey’s father and Benny’s daughter—are still linked by that recipe.
