In math for couples, we re-visit the past to discover our place in the contemporary world. A long-dead father watches his daughter work on her Mac, a woman converses with a photo of her young self. Adele Graf leads us on a journey that is rich and hopeful, evoking powerful nostalgia even if we've never been to the places described. When these poems release us back to our current lives, we feel restored to savour the warmth in a "glad red hat" and the love that arrives "still summer lush."
