Mercutio has never been in love. Not unless you count a boy whose face he can barely remember. Not unless you count the world. [loc. 2328]
Mercutio Guertio (yes, that Mercutio) meets Dante Alighieri at the Battle of Campaldino in 1289: they are caught in a freak storm -- where they glimpse spectral armies, and becomes certain that there is a third man with them -- but stumble back to the carnage of the battlefield, and subsequently become friends. Mercurio, though, has been changed: he sees people who are not there, and does not recognise the stars in the night sky. Then Dante, grieving the death of 'his' Beatrice, is pulled into Faerie, where he wanders in a dark wood...
Mercutio does not know the way to Faerie, but he's encountered their Queen, and she tells him that he can rescue Dante if he can find a doorway. Brunetto Latini, Dante's friend and teacher, suggests that Mercutio joins the expedition of the Vivaldi brothers, who want to find a route to Asia by sailing west from Spain. Surely Faerie is on the other side of the world, and thus can be found on the way to Asia?
En route, Mercutio encounters a female pope, sailors from China and Africa, a helpful friar who supplies a medicine made of henbane, and a hermit who claims to be the son of Abelard and Heloise. He's haunted by a silent, mysterious man who people seem to think is his brother: and he's differently haunted by memories of his lost love, a boy who he called Blackbird after mishearing the other's name as 'I fly'.
This is a splendid novel, packed with cosmology, Italian history (Guelphs and Ghibellines), Tarot imagery, and perfidious fae. The fantastical elements blend folk tales, ballads and mythology: to me, Heartfield's Faerie had a distinctly medieval feel, reminiscent of Chaucer and Boccaccio. The novel also provides an origin story for Dante's Divine Comedy: and, of course, Mercutio has to get to Verona and encounter the warring Montecchi and Cappalletti factions...
But at its heart, Mercutio is the story of the friendship between Mercutio and Dante, and the implacable vengeance of the Faerie Queen. Mercutio is vividly rendered, with a blend of self-doubt, cynicism and joie de vivre that seems fitting for the changes he witnesses in the world around him. I liked him a great deal: and I'll look out for Heartfield's other novels, because her prose is readable and this story full of surprises.
