Eugene “Geno” Miles is living out his final days in a nursing home, bored, curmudgeonly, and struggling to connect with his new nursing assistant, Angel, who is understandably skeptical of Geno’s insistence on having lived not just one life but many—all the way back to medieval Spain, where, as a petty thief, he first lucked upon true love only to lose it, and spend the next thousand years trying to recapture it.

Who is Geno? A lonely old man clinging to his delusions and rehearsing his fantasies, or a legitimate anomaly, a thousand-year-old man who continues to search for the love he lost so long ago?

As Angel comes to learn the truth about Geno, so, too, does the reader, and as his miraculous story comes to a head, so does the biggest truth of that love—timeless, often elusive—is sometimes right in front of us.

When a book keeps me turning pages long after bedtime, I often ask myself why. Is there a delicious mystery demanding to be solved? A heart-pounding stretch of action and tension? Or is it simply a superbly told story granting me temporary residence in a world I don’t want to leave?

In the case of Jonathan Evison’s Again and Again: All of the above.

We don’t know who Geno Miles is. Geno Miles is a present-day centenarian who keeps his nursing-home staff on their toes with his curmudgeonly quirks while carrying deep wounds in his soul. Geno Miles is a street urchin who runs afoul of the powerful in medieval Spain, growing into his own bravery and risking everything for his one true love. Geno Miles is—and, honestly, this one is my favorite—Oscar Wilde’s cat, selectively spoiled in an apartment in Chelsea, believing his owner might be a reincarnated version of that one true love.

Centuries separate Geno from his love, but he still believes. It’s a fantastic story. Compelling enough to draw in Angel, a young man who works at the nursing home and forges an unlikely friendship with Geno. Compelling enough to keep me, as a reader, up until dawn, unable to put the book down.

Hope. That’s it, I think. We’ve got mystery and action and unforgettable characters but there is also an unbreakable thread of hope running through Again and Again. I can’t think of anything our world needs more right now.
